ESQL elements and statements Syntax 334 Related statements DECLARE CURSOR, OPEN, CLOSE GET DIAGNOSTICS Retrieves information about the execution of the previous SQL statement from the SQL diagnostics area. The diagnostics area is a data structure that contains information about the execution status of the most recent SQL statement. Specifically, GET DIAGNOSTICS extracts information about the SQL statement as a whole from the SQL diagnostics area’s header component. Note: The GET DIAGNOSTICS EXCEPTION number extracts detail information. GET DIAGNOSTICS :param = header_info_item [ , :param = header_info_item ] , ... ; :param A host-language variable to receive the information returned by the GET DIAGNOSTICS statement. The host-language program must declare a param compatible with the SQL data type of the information item. header_info_item One of the following keywords, which returns associated information about the diagnostics area or the SQL statement: Syntax NUMBER | MORE | COMMAND_FUNCTION | DYNAMIC_FUNCTION | ROW_COUNT NUMBER MORE The number of detail areas in the diagnostics area. Currently, NUMBER is always 1. NUMBER is type NUMERIC with a scale of 0. A one-character string with a value of Y (all conditions are detailed in the diagnostics area) or N (all conditions are not detailed) that tells whether the diagnostics area contains information on all the conditions resulting from the statement. COMMAND_FUNCTION Contains the character-string code for the statement (as specified in the SQL standard), if the statements is a static SQL statement. If the statement is a dynamic statement, contains the character string EXECUTE or EXECUTE IMMEDIATE.
DYNAMIC_FUNCTION ESQL elements and statements Contains the character-string code for the statement (as specified in the SQL standard). For dynamic SQL statements only (as indicated by EXECUTE or EXECUTE IMMEDIATE in the COMMAND_FUNCTION item). ROW_COUNT The number of rows affected by the SQL statement. Example The GET DIAGNOSTICS example extracts header information about the last SQL statement executed. The information is assigned to host variables that are defined in the DECLARE SECTION of an embedded SQL program, as shown in the following example: Syntax GET DIAGNOSTICS :num = NUMBER, :cmdfunc = COMMAND_FUNCTION ; The GET DIAGNOSTICS statement itself does not affect the contents of the diagnostics area. This means applications can issue multiple GET DIAGNOSTICS statements to retrieve different items of information about the same SQL statement. Related statements GET DIAGNOSTICS EXCEPTION, WHENEVER GET DIAGNOSTICS EXCEPTION Retrieves information about the execution of the previous SQL statement from the SQL diagnostics area. The diagnostics area is a data structure that contains information about the execution status of the most recent SQL statement. Specifically, GET DIAGNOSTICS EXCEPTION extracts information about the SQL statement as a whole from the SQL diagnostics area’s detail component. The detail area contains information for a particular condition (an error, warning, or success condition) associated with execution of the last SQL statement. The diagnostics area can potentially contain multiple detail areas corresponding to multiple conditions generated by the SQL statement described by the header. The SQL diagnostics area currently supports only one detail area. Note: The GET DIAGNOSTICS statement extracts header information. GET DIAGNOSTICS EXCEPTION number :param = detail_info_item [, :param = detail_info_item ] , ... ; EXCEPTION number Specifies that GET DIAGNOSTICS EXCEPTION extracts detail information. number specifies which of multiple detail areas GET DIAGNOSTICS extracts. Currently, number must be the integer 1. 335
