Detailed Description

Sql_cmd_get_diagnostics represents a GET DIAGNOSTICS statement.

The GET DIAGNOSTICS statement retrieves exception or completion condition information from a diagnostics area, usually pertaining to the last non-diagnostic SQL statement that was executed.

Definition at line 30 of file sql_get_diagnostics.h.

Constructor & Destructor Documentation

Sql_cmd_get_diagnostics::Sql_cmd_get_diagnostics ( Diagnostics_information *  info )

inline

Constructor, used to represent a GET DIAGNOSTICS statement.

Parameters

info	Diagnostics information to be obtained.

Definition at line 38 of file sql_get_diagnostics.h.

Member Function Documentation

bool Sql_cmd_get_diagnostics::execute ( THD *  thd )

virtual

Execute this GET DIAGNOSTICS statement.

Parameters

thd	The current thread.

Remarks

Errors or warnings occurring during the execution of the GET DIAGNOSTICS statement should not affect the diagnostics area of a previous statement as the diagnostics information there would be wiped out. Thus, in order to preserve the contents of the diagnostics area from which information is being retrieved, the GET DIAGNOSTICS statement is executed under a separate diagnostics area. If any errors or warnings occur during the execution of the GET DIAGNOSTICS statement, these error or warnings (conditions) are appended to the list of the original diagnostics area. The only exception to this is fatal errors, which must always cause the statement to fail.

Return values

false	on success.
true	on error

Implements Sql_cmd.
