Re: Can IWS Call Stored Procedures?

ANSWERS BELOW

1. Can an IWS service call a SQL stored procedure? It is one thing
to execute SELECT, UPDATE, INSERT, and DELETE statements. It is
another thing to CALL stored procedures.

YES.

2. Are there limiting conditions when using IWS to call SQL stored
procedures?

NOT THAT I KNOW OF.



3. Are there size limits on parameters that can be handled with this
approach? For example, suppose I want a stored procedure to return a
row set as a JSON string in a CLOB (10M) parameter. Could an IWS
service that calls this stored procedure handle the CLOB parameter?
Are there any limits on parameter size other than the limit of a CLOB
itself?


NO LIMITS OTHER THAN THOSE IMPOSED BY SYSTEM, JAVA TOOLBOX JDBC DRIVER. IF
YOU PLAN ON RETURNING LARGE OBJECTS THEN YOU SHOULD ENSURE SERVER HAS
ENOUGH MEMORY.
