![]() ![]() In brackets provide values for input parameters. When executing the function, provide whole name of the function. How to query Table Functions?Ĭalling table Functions in SQL console is very easy. After writing Table Function definition activate it and make sure that there is no error after activation.īe aware that any of Data Definition ( CREATE, ALTER, etc.) or Data Manipulation ( INSERT, UPDATE etc.) operators are not allowed in Table Functions.Preserve the columns order, column names (case sensitive) and their data types consistent with the select statement Add semicolon (“ ”) at the end of the statement. ![]() Add leading colons (“:”) when calling each parameter. Apply input parameters in the WHERE clause. Add RETURN phrase before the final select statement. When applying default value for schema mapping, in the query you should use table names without schemas i.e simply use “ ORDERS” instead of “ DEV“.” ORDERS“. If you provide the default schema in the definition of Table Function, then while transporting this schema will be automatically replaced with the schema of target system (based on schema mapping). in development system you are using “ DEV” schema, but on production all tables are placed in “ PROD” schema. This is needed when you transport the function between instances with different schemas i.e. This is needed when you want to parametrize Table Function. Provide input parameters including data types.
