Creating stored procedure in derby database in netbeans 8.0.1 - stored-procedures

I am using netbeans 8.0.1 and derby database. While creating Stored Procedure I am getting following error :
Error code -1, SQL state 42X01: Syntax error: Encountered "(" at line
2, column 39.
Here is my Stored Procedure Code
DELIMITER $$
CREATE PROCEDURE insertSignUp(IN uname VARCHAR(50), IN pwd VARCHAR(50), IN fname VARCHAR(20), IN mname VARCHAR(20), IN lname VARCHAR(20), IN dob DATE(10), IN clg VARCHAR(20), IN workInfo VARCHAR(20), IN contact VARCHAR(20))

update a column inside a stored procedure

I have two snowflake tables as below
TEST1
create OR REPLACE table TEST1 (
id varchar(100),
name varchar(100),
org VARCHAR(64)
);
INSERT INTO TEST1 values (100, 'ABC', null);
INSERT INTO TEST1 values (200, 'XYZ', null);
INSERT INTO TEST1 values (300, 'VBN', null);
CONTROL
create OR REPLACE table CONTROL (
KEY_COLUMNS VARCHAR,
TABLE_NAME VARCHAR,
org VARCHAR
);
INSERT INTO CONTROL values ('id,name, address','TEST1','Z');
INSERT INTO CONTROL values ('id,name, address','TEST2','T');
I have created a stored procedure which updates column 'org' in TEST1 table with the values from CONTROL table (column org) where table name is TEST1.
CREATE OR REPLACE PROCEDURE TEST(source_tbl VARCHAR)
RETURNS string
LANGUAGE SQL
AS
$$
DECLARE
query1 STRING;
BEGIN
QUERY1 := 'update TEST1 set ORG = (select org from CONTROL WHERE TABLE_NAME = ''source_tbl'');';
EXECUTE IMMEDIATE :QUERY1;
RETURN :QUERY1;
END;
$$;
call TEST((select TABLE_NAME from CONTROL WHERE TABLE_NAME = 'TEST1'));
expected output
My output
The parameter should be bound variable instead of passing as the string constant ''source_tbl'':
CREATE OR REPLACE PROCEDURE TEST(source_tbl VARCHAR)
RETURNS string
LANGUAGE SQL
AS
$$
DECLARE
query1 STRING;
BEGIN
QUERY1 := 'update TEST1 set ORG = (select org from CONTROL WHERE TABLE_NAME = ?);';
EXECUTE IMMEDIATE :QUERY1 USING (SOURCE_TBL);
RETURN :QUERY1;
END;

Dynamic Creation of External Tables in Synapse

I have a json string which is the result of Get Metadata activity in data factory in the following format: {"structure": [{"name": "Id","type": "String"},{"name": "IsDeleted","type": "Boolean"},{"name": "RowVersion","type": "Byte[]"}, {"name": "ModelId","type": "String"}]
This json is showing the schema of parquet file. I pass this json along with the parquet filename and uctnow() to a stored procedure to create a table of schema for that file with the following code
CREATE OR ALTER PROCEDURE [CreateExternalTables] (
#schema NVARCHAR (MAX), #tableName NVARCHAR(MAX), #ExecTime NVARCHAR(MAX)
) AS
BEGIN
IF OBJECT_ID('tempdb..#tables_to_create', 'U') IS NOT NULL
DROP TABLE #tables_to_create
CREATE TABLE #tables_to_create (
tableName NVARCHAR (MAX),
fieldOrder NVARCHAR (MAX),
fieldName NVARCHAR (MAX),
fieldType NVARCHAR (MAX),
translatedType NVARCHAR (MAX),
executeTime NVARCHAR (MAX)
)
BEGIN
WITH Fields (fieldOrder, fieldName, fieldType) AS (
SELECT
[key] AS fieldOrder,
JSON_VALUE([value], '$.name') AS fieldName,
JSON_VALUE([value], '$.type') AS fieldType
FROM
OPENJSON(#schema)
)
INSERT INTO
#tables_to_create(
tableName,
fieldOrder,
fieldName,
fieldType,
translatedType,
executeTime
)
SELECT
#tableName,
fieldOrder,
fieldName,
fieldType,
CASE
WHEN fieldType = 'Single' THEN 'real'
WHEN fieldType = 'Boolean' THEN 'bit'
WHEN fieldType = 'Double' THEN 'float'
WHEN fieldType = 'Int64' THEN 'bigint'
ELSE NULL
END AS translatedType,
#ExecTime
FROM
Fields
END
END;
The overall setup is like below:
But I receive the following error which I'm not sure why:
What I would like to do is to create this temo table in stored procedure in order to create external tables in a automatic way.
To be precise I'm following this link to do it:
create-external-dataset
Any help is highly appreciated.
UPDATE
After solving the first problem with #wBob 's help I follow the rest of the link to create the external tables with the following which I inserted into my stored procedure:

Fields
END

Declare #folderPath nvarchar(max);
SET
#sqlCommand = 'IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N''[dbo].[' + #tableName + ']'') AND type in (N''U''))

BEGIN
DECLARE #key int
SELECT
#key = MIN(fieldOrder)

DECLARE #fieldName VARCHAR(50)
DECLARE #translatedType VARCHAR(50)
SELECT
#fieldName = fieldName,

)
WITH

LOCATION = ''/' + /main/json/ + ''',
DATA_SOURCE = DataLakeStaged,
FILE_FORMAT = StagedParquet
)'
EXEC(#sqlCommand)
END;
However I receive the following error:
As per the error message, queries are not supported in the conditions of WHILE statement in Azure Synapse Analytics. Dedicated SQL pools are MPP systems that have some slight differences from box-product SQL Server and Azure SQL DB and more generally, loops are a pattern that don't translate that well. You should consider creating a stored procedure that does not loop and leave any looping required to the For Each activity in Azure Data Factory (ADF) / Synapse Pipelines which can loop in parallel.
If you do require a loop, there are multiple examples of doing loops in dedicated SQL pools online, but there is a good example in the official documentation, reproduced here in the event the link moves:
-- First, create a temporary table containing a unique row number used to identify the individual statements:
CREATE TABLE #tbl
WITH
( DISTRIBUTION = ROUND_ROBIN
)
AS
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS Sequence
, [name]
, 'UPDATE STATISTICS '+QUOTENAME([name]) AS sql_code
FROM sys.tables
;
-- Second, initialize the variables required to perform the loop:
DECLARE #nbr_statements INT = (SELECT COUNT(*) FROM #tbl)
, #i INT = 1
;
-- Now loop over statements executing them one at a time:
WHILE #i <= #nbr_statements
BEGIN
DECLARE #sql_code NVARCHAR(4000) = (SELECT sql_code FROM #tbl WHERE Sequence = #i);
EXEC sp_executesql #sql_code;
SET #i +=1;

How to Execute Macro through Stored Procedure

I have created one macro in Teradata, now wish to call that macro through Stored Procedure (in Teradata only). The SQL part belongs to macro.
I wrote this procedure in case if execution of macro is not possible through procedure.
Kindly suggest both the option.

No idea, what to add between the word 'A' and ')'. Tried all the possibility but not successful. Not sure how to pass the value of SQL into the 'count' as later call procedure condition is based on that count only.

How to read output value from stored procedure in c#?

Here is my stored procedure:
ALTER PROCEDURE sp_searchupdate
(
#id int,
#id_student int,
#output varchar(50) output,
#Tamil Varchar (100),
#English varchar (50),
#Maths Varchar (50),
#Science Varchar (50),
#SocialScience Varchar (50)
)
AS
IF EXISTS (SELECT * FROM studentresult WHERE id=#id)
BEGIN
UPDATE studentresult SET Tamil = #Tamil,English = #English, Maths = #Maths,Science = #Science,SocialScience = #SocialScience WHERE id = #id
SET #output='Updated'
RETURN
END
Else
BEGIN
IF EXISTS (SELECT * FROM student WHERE id=#id_student)
SET #output='EXIST'
RETURN
BEGIN
INSERT into studentresult (id_student,Tamil,English,Maths,Science,SocialScience) values (#id_student,#Tamil,#English,#Maths,#Science,#SocialScience)
SET #output='Inserted'
RETURN
END
END
If inserted data in front-end it need to shows 'inserted' or update means 'updated' or else 'exist'.
But for the above query didn't show notification message.
May i know, what my mistake in my code?
Can anyone guide me, I'M new stored procedure and .net.
Thanks,
It's rather unclear exactly what you are trying to achieve - why would you only insert into the studentresult record if the student record did NOT exist? Anyway, currently if no studentresult record exists then the procedure will always return after the check for the student record. There is no BEGIN...END after the IF EXISTS so only the first statement after the IF will be dependent on the result. Try:
ALTER PROCEDURE sp_searchupdate
(
#id int,
#id_student int,
#output varchar(50) output,
#Tamil Varchar (100),
#English varchar (50),
#Maths Varchar (50),
#Science Varchar (50),
#SocialScience Varchar (50)
)
AS
BEGIN
IF EXISTS (SELECT * FROM studentresult WHERE id=#id)
BEGIN
UPDATE studentresult SET Tamil = #Tamil,English = #English, Maths = #Maths,Science = #Science,SocialScience = #SocialScience WHERE id = #id
SET #output='Updated'
END
Else
BEGIN
IF EXISTS (SELECT * FROM student WHERE id=#id_student)
BEGIN
SET #output='EXIST'
END
ELSE
BEGIN
INSERT into studentresult (id_student,Tamil,English,Maths,Science,SocialScience) values (#id_student,#Tamil,#English,#Maths,#Science,#SocialScience)
SET #output='Inserted'
END
END
RETURN
END

Firebird and stored procedures: if exists then else

I'm trying to create a stored procedure for firebird 2.1 (this is the version which is to be used)
But am getting a bit stuck, so any help is appreciated.
The final version should compare 4 values agains the table, and retreive either the primaryid if the value exists, or create the new entry in the table, and return the new primaryid.
But I get stuck with only one value lookup, and it's not even using the variable yet.
SET TERM ^ ;
CREATE PROCEDURE TESTSP
( A Varchar(64) )
RETURNS
( RESULT Integer )
AS
BEGIN
IF (EXISTS (SELECT PRIMARYID FROM TABLENAME WHERE FIELD = 'Some string')) then
SELECT PRIMARYID FROM TABLENAME WHERE FIELD = 'Some string' into :primaryid;
result = PRIMARYID;
ELSE
INSERT INTO TABLENAME (FIELD) VALUES ('Some string');
result = gen_id(GEN_TABLEID, 0);
END^
SET TERM ; ^
I get a "Token unknown" for the Else command.
Update after responses:
Now I want to use the 4 variables and return the 4 results.
I think I need a for loop to do so, but with firebird, the for function means something else.
So what would be the way to go?
SET TERM ^ ;
CREATE PROCEDURE TESTSP
( value1 Varchar(64) )
RETURNS
( RESULT1 Integer )
AS
BEGIN
IF (EXISTS (SELECT PRIMARYID FROM TABLENAME WHERE FIELD = :value1)) then
SELECT PRIMARYID FROM TABLENAME WHERE FIELD = value1 into :result1;
ELSE BEGIN
result1 = gen_id(GEN_TABLEID, 1);
INSERT INTO TABLENAME (PRIMARYID, FIELD) VALUES (:result1, :value1);
END
suspend;
END^
SET TERM ; ^
As Tico already answered you have to use begin / end to group multiple statements in then / else part. The error abut column PRIMARYID being unknown is because you reference to it without having declared a local variable for it. Try this:
CREATE PROCEDURE TESTSP ( A Varchar(64) )
RETURNS ( RESULT Integer )
AS
BEGIN
-- initialize the result
Result = NULL;
-- check is the string already in table
SELECT PRIMARYID FROM TABLENAME WHERE FIELD = 'Some string' into :Result;
IF (Result is NULL) then
INSERT INTO TABLENAME(PRIMARYID, FIELD) VALUES(gen_id(GEN_TABLEID, 1), 'Some string') RETURNING PRIMARYID INTO :Result;
END^
I think your stored procedure should look like this:
SET TERM ^ ;
CREATE PROCEDURE TESTSP
( A Varchar(64) )
RETURNS ( result Integer )
AS
BEGIN
IF (EXISTS (SELECT PRIMARYID
FROM TABLENAME
WHERE FIELD = 'Some string')) then
SELECT PRIMARYID
FROM TABLENAME
WHERE FIELD = 'Some string'
into :result;
ELSE BEGIN
result = gen_id(GEN_TABLEID, 1);
INSERT INTO TABLENAME
(PRIMARYID, FIELD)
VALUES (:result, 'Some string');
END
END^
SET TERM ; ^
If you have multiple instruction for then and/ or else clause you must use BEGIN ... END-block!
SET TERM ^ ;
CREATE PROCEDURE TESTSP
( A Varchar(64) )
RETURNS
( RESULT Integer )
AS
BEGIN
IF (EXISTS (SELECT PRIMARYID FROM TABLENAME WHERE FIELD = 'Some string')) then
BEGIN
SELECT PRIMARYID FROM TABLENAME WHERE FIELD = 'Some string' into :primaryid;
result = PRIMARYID;
END
ELSE
BEGIN
INSERT INTO TABLENAME (FIELD) VALUES ('Some string');
result = gen_id(GEN_TABLEID, 0);
END
END^
SET TERM ; ^
