The CFPROCPARAM tag is nested within a CFSTOREDPROC tag. You use it to specify parameter information, including type, name, value, and length.

TYPE

Optional. Indicates whether the passed variable is an input, output or input/output variable. Default is IN.

VARIABLE

Required for OUT and INOUT parameters. This is the ColdFusion variable name that you use to reference the value that the output parameter represents after the call is made to the stored procedure.

DBVARNAME

Required if named notation is desired. This is the parameter name. This corresponds to the name of the parameter in the stored procedure.

VALUE

Required for IN and INOUT parameters. This corresponds to the actual value that ColdFusion passes to the stored procedure.

CFSQLTYPE

Required. This is the SQL type that the parameter (any type) will be bound to. The CFSQLTypes are as follows:

CF_SQL_BIGINT CF_SQL_IDSTAMP CF_SQL_REAL
CF_SQL_CHAR CF_SQL_INTEGER CF_SQL_SMALLINT
CF_SQL_DATE CF_SQL_LONGVARCHAR CF_SQL_TIME
CF_SQL_DECIMAL CF_SQL_MONEY CF_SQL_TIMESTAMP
CF_SQL_DOUBLE CF_SQL_MONEY4 CF_SQL_TINYINT
CF_SQL_FLOAT CF_SQL_NUMERIC CF_SQL_VARCHAR

MAXLENGTH

Optional. Maximum length of the parameter.

SCALE

Optional. Number of decimal places of the parameter.

NULL

Optional. Specify Yes or No. Indicates whether the parameter is passed as a NULL. If you specify Yes, the tag ignores the VALUE attribute.

Usage

Use this tag to identify stored procedure parameters and their data type. Code one CFPROCPARAM tag for each parameter. The parameters you code vary, based on parameter type and DBMS. Additionally, the order in which you code CFPROCPARAM tags matters, depending on whether the stored procedure was coded using positional notation or named notation:

Output variables will be scoped with the name of the VARIABLE attribute that was passed to the tag.
