I'm trying to execute Snowflake Stored Procedure in Matilion Using Sql Script component.
But i'm getting error as Unknown user defined function.
Can someone help me to call the procedure using Matilion Job.
Thank You !
That looks like a name resolution error. Snowflake does not recognize the name of the stored procedure. You will see the same generic error message when trying to call a procedure that really does not exist...
You most likely need to
qualify the procedure name with a database and a schema
put the names inside double-quotes if they are case sensitive.
In the Matillion stored procedure article there is an example CALL "${environment_database}"."${examples_schema}"."audit"('START', ${run_history_id}, NULL)

I am presently updating a procedure with multiple EXEC lines such as:
EXEC databasename.tablename.pr_sys_drop_Object 'zt_Staging_of_class'
yet nowhere have I found the definition of EXEC in this context.
If it's a full three part name where the middle part is not the name of a table but of a schema a kind of SQL namespace. So in that context pr_sys_drop_Object is a stored procedure in a separate schema.
If you look in the named database, in the named schema you'll probably find a stored procedure called pr_sys_drop_Object.
Execute is a sql server keyword see the docs here for more details. It is used to execute stored procedures or raw sql.
In your case it seems to be executing the procedure databasename.tablename.pr_sys_drop_Object and passing in 'zt_Staging_of_class' as a parameter to that procedure.
I am relatively new to Pervasive Control Center and I was wondering if I wanted to test a stored Procedure to see its results, how would I simply select that stored proc? I have:
Select SP_test_getMeasure06
I am sure I am missing something because I know this is legal my syntax must be off slightly.
Thanks in advance!
You can execute a stored procedure using either Call or Exec. For example:
exec SP_test_getMeasure06
You'll need to make sure your stored procedure uses the RETURNS clause to get data back. For more information check out the Stored Procedure docs.
I have created a stored procedure and can see it under the stored procedure node, but when trying to execute it doesn't find the procedure.
Under stored procedure node it is called dbo.CopyTable
exec CopyTable
CopyTable is undefined in red saying it does not exist. Why?
Even if I right-click on the procedure and say script stored procedure as execute to - the code it generates is underlined in red and cant find stored procedure either.
Ensure that the database selected contains the stored procedure CopyTable
USE YourDatabase
EXEC CopyTable
Try adding dbo and selecting the right database,
USE databaseName
GO
EXEC dbo.CopyTable
GO
Execute a Stored Procedure
Most likely you are just in the wrong database in the query window, you can specify the database like this:
EXEC [yourDBName].dbo.CopyTable
Reading on how to Execute a Stored Procedure
Considering your updated question:
Even if i rightclick on the procedure and say script stored procedure
as execute to - the code it generates is underlined in red and cant
find stored procedure either.
This could happen if your stored procedure is invalid. Please double-check the validity of the SPROC and ensure the tables it references exist, etc.
Try running your CREATE PROCEDURE. Highlight it, f5 it, and then make sure it runs before you call it elsewhere.
Maybe in your procedure you've accidentally cut-pasted your script name (dbo.CopyTable), say something like...
SELECT * FROM dbo.CopyTable
WHERE ClientId = #ClientId
RETURN
Then when you call your proc you get 'invalid object name dbo.CopyTable' and assume sql is having trouble finding the stored-proc ... which isn't the problem, its finding and running the proc but its actually a problem within the proc.
How can I call a stored procedure in the same schema without specifying the full schema name when coding another stored procedure. These are SQL PL procedures within DB2.
First SP:
CREATE PROCEDURE MYSCHEMA.SP_TEST
LANGUAGE SQL
BEGIN
END
Creating a SP calling this SP directly without a schema name causes a compilation error:
CREATE PROCEDURE MYSCHEMA.SP_TEST2
LANGUAGE SQL
BEGIN
CALL SP_TEST();
END
It will throw:
No authorized routine named "SP_TEST" of type "PROCEDURE" having compatible arguments was found.. SQLCODE=-440, SQLSTATE=42884, DRIVER=3.53.71
Directly giving the full schema name works:
CREATE PROCEDURE MYSCHEMA.SP_TEST2
LANGUAGE SQL
BEGIN
CALL MYSCHEMA.SP_TEST();
END
However if I ever move to a different schema I will have to replace that references all over the place. Is there a suitable workaround or nicer solution to the problem?
The CURRENT PATH special register is used to resolve calls to unqualified stored procedures and functions. CURRENT SCHEMA is used to resolve unqualified object names.
By default, CURRENT PATH has IBM functions plus your AUTHID:
$ db2 "values substr(current path,1,60)"
1
------------------------------------------------------------
"SYSIBM","SYSFUN","SYSPROC","SYSIBMADM","IBJORHOV"
1 record(s) selected.
You can modify this with the SET CURRENT PATH statement.
When you create a stored procedure, DB2 takes note of the value of CURRENT PATH at compilation time and uses them to resolve unqualified stored procedure and function calls within the stored procedure. The same logic applies for CURRENT SCHEMA and unqualified table names.
So the proper way to allow unqualified procedure and function calls within a stored procedure is to set the CURRENT PATH register and then creating the procedure.
Ommitting SCHEMA name is discouraged. Keep your schema names in your calls. If you move to a different schema, you have to do this by extracting/altering the SQL script anyway.
The SET SCHEMA command allows you to change the current schema:
SET CURRENT SCHEMA FOO;
CALL MY_PROC_THAT_RESIDES_IN_FOO();
It is not so easy to use set the schema to a dynamic value, though. You would have to either:
Do something with host variables (if you are within a calling application) or
Build and execute a dynamic SQL statement string.
At that point it is probably becoming more trouble than it's worth.
More information can be found at the documentation for the SET SCHEMA command.
While running a procedure it gives error like Insert Error: Column name or number of supplied values does not match table definition. But when I run same set of queries without any procedure it run fine. Can someone tell me what 's the problem
I'm going to guess that your stored procedure is asking for a certain set of parameters, but you are supplying a different set of arguments. When you call the stored procedure, make sure any arguments given are correct for what is expected.
Either that or the stored procedure itself has an error trying to talk to a database table and getting the schema wrong.
