| .SH "NAME" |
| tdbc::mapSqlState \- Map SQLSTATE to error class |
| .SH "SYNOPSIS" |
| .nf |
| package require \fBtdbc 1.0\fR |
| |
| \fBtdbc::mapSqlState\fR \fIsqlstate\fR |
| .fi |
| .BE |
| .SH "DESCRIPTION" |
| .PP |
| The \fBtdbc::mapSqlState\fR command accepts a string that is expected |
| to be a five-character 'SQL state' as returned from a SQL database when |
| an error occurs. It examines the first two characters of the string, |
| and returns an error class as a human- and machine-readable name (for example, |
| \fBFEATURE_NOT_SUPPORTED\fR, \fBDATA_EXCEPTION\fR or |
| \fBINVALID_CURSOR_STATE\fR). |
| .PP |
| The TDBC specification requires database drivers to return a description |
| of an error in the error code when an error occurs. The description is |
| a string that has at least four elements: "\fBTDBC\fR \fIerrorClass\fR |
| \fIsqlstate\fR \fIdriverName\fR \fIdetails...\fR". The \fBtdbc::mapSqlState\fR |
| command gives a convenient way for a TDBC driver to generate the |
| \fIerrorClass\fR element given the SQL state returned from a database. |
