22.2.3.45 `mysql_query()'
.........................
`int mysql_query(MYSQL *mysql, const char *query)'
Description
...........
Executes the SQL query pointed to by the null-terminated string `query'.
Normally, the string must consist of a single SQL statement and you
should not add a terminating semicolon (`;') or `\g' to the statement.
If multiple-statement execution has been enabled, the string can contain
several statements separated by semicolons. C API multiple
queries.
`mysql_query()' cannot be used for queries that contain binary data; you
should use `mysql_real_query()' instead. (Binary data may contain the
`\0' character, which `mysql_query()' interprets as the end of the
query string.)
If you want to know whether the query should return a result set, you
can use `mysql_field_count()' to check for this.
`mysql_field_count()' mysql_field_count.
Return Values
.............
Zero if the query was successful. Non-zero if an error occurred.

`CR_SERVER_GONE_ERROR'

`CR_SERVER_LOST'
