CREATE PROCEDURE
Valid in: SQL, ESQL, OpenAPI, ODBC, JDBC, .NET
The CREATE PROCEDURE statement creates a database procedure.
The CREATE PROCEDURE statement has the following format:
[EXEC SQL] [CREATE | CREATE OR REPLACE] PROCEDURE [schema.]proc_name
[[(set_param_name [=] SET OF]
([param_mode] param_name [=] param_type
[WITH | NOT DEFAULT] [WITH | NOT NULL]
{, [param_mode] param_name [=] param_type
[WITH | NOT DEFAULT] [WITH | NOT NULL]})[)]]
[RESULT ROW [result_row_name] ([result_column_name]
(result_type [WITH | NOT DEFAULT] [WITH | NOT NULL]
{, result_type [WITH | NOT DEFAULT] [WITH | NOT NULL]}) =|AS
[declare_section]
BEGIN
statement {; statement}[;]
END
CREATE OR REPLACE
Recreates the procedure if it already exists, and preserves the object ID and any existing dependent objects.
proc name
Defines the name of the procedure. This must be a valid object name.
set_param_name
Defines the name of the SET OF parameter. This must be a valid object name. The SET OF parameters are referenced like base tables in the body of the procedure.
param_name
Defines the name of a procedure parameter. This must be a valid object name. Parameters can be passed by value or by reference.
param_mode
Assigns one of the following modes to the procedure parameter:
IN
Declares the parameter as an input only parameter.
OUT
Declares the parameter as an output only parameter.
INOUT
Declares the parameter as one that passes a value into the procedure and returns it, possibly modified, to the calling program.
param_type
Specifies the data type of the associated parameter. The data type can be any legal SQL data type, and the WITH | NOT NULL clause can be part of the specification.
declare_section
A list of local variables for use in the procedure. For more information, see
DECLARE.
statement
Local variable assignments and any of the statements listed in the text of the CREATE PROCEDURE description.
result_row_name
Assigns a name to the result row.
Note: A result row name is required when result columns are to be named. A result row can be unnamed if none of the columns are to be named.
result_column_name
Assigns a name to a result column. This name can then be used in a query.
result_type
The data type of the associated entry in a RETURN ROW statement. The data type can be any legal SQL data type, and the WITH | NOT NULL clause can be part of the specification. For more information, see
RETURN ROW.
Note: If II_DECIMAL is set to comma, you must follow any comma required in SQL syntax (such as a list of table columns or SQL functions with several parameters) by a space. For example:
SELECT col1, IFNULL(col2, 0), LEFT(col4, 22) FROM version;
