typedef void *(* callback_function) (void *) |
typedef MYSQL_THD(* mysql_current_session_t) () |
typedef int(* mysql_extract_prepared_params_t) (MYSQL_THD thd, int *positions) |
Stores in 'positions' the positions in the last parsed query of each parameter marker('?').
Positions must be an already allocated array of at least mysql_parser_service_st::mysql_get_number_params() size. This works only if the last query was parsed as a prepared statement.
thd | The session in which the query was parsed. |
positions | An already allocated array of at least mysql_parser_service_st::mysql_get_number_params() size. |
typedef void(* mysql_free_string_t) (MYSQL_LEX_STRING string) |
Frees a string buffer allocated by the server.
string | The string whose buffer will be freed. |
typedef MYSQL_LEX_STRING(* mysql_get_normalized_query_t) (MYSQL_THD thd) |
Returns the current query in normalized form.
This string is managed by the server and should not be freed by a plugin.
thd | The session in which the query was submitted. |
typedef int(* mysql_get_number_params_t) (MYSQL_THD thd) |
Returns the number of parameters ('?') in the parsed query.
This works only if the last query was parsed as a prepared statement.
thd | The session in which the query was parsed. |
typedef MYSQL_LEX_STRING(* mysql_get_query_t) (MYSQL_THD thd) |
Returns the current query string.
This string is managed by the server and should not be freed by a plugin.
thd | The session in which the query was submitted. |
typedef int(* mysql_get_statement_digest_t) (MYSQL_THD thd, unsigned char *digest) |
Returns the digest of the last parsed statement in the session.
thd | The session in which the statement was parsed. | |
[out] | digest | An area of at least size PARSER_SERVICE_DIGEST_LENGTH, where the digest is written. |
0 | Success. |
1 | Parse error. |
typedef int(* mysql_get_statement_type_t) (MYSQL_THD thd) |
typedef Item* MYSQL_ITEM |
typedef MYSQL_LEX_STRING(* mysql_item_string_t) (MYSQL_ITEM item) |
Renders the MYSQL_ITEM as a string and returns a reference in the form of a MYSQL_LEX_STRING.
The string buffer is allocated by the server and must be freed by mysql_free_string().
item | The literal to print. |
typedef void(* mysql_join_thread_t) (struct my_thread_handle *thread_handle) |
typedef MYSQL_THD(* mysql_open_session_t) () |
typedef int(* mysql_parse_t) (MYSQL_THD thd, const MYSQL_LEX_STRING query, unsigned char is_prepared, sql_condition_handler_function handle_condition, void *condition_handler_state) |
Parses the query.
thd | The session in which to parse. |
query | The query to parse. |
is_prepared | If non-zero, the query will be parsed as a prepared statement and won't throw errors when the query string contains '?'. |
handle_condition | Callback function that is called if a condition is raised during the preparation, parsing or cleanup after parsing. If this argument is non-NULL, the diagnostics area will be cleared before this function returns. |
condition_handler_state | Will be passed to handle_condition when called. Otherwise ignored. |
0 | Success. |
1 | Parse error. |
typedef void(* mysql_set_current_database_t) (MYSQL_THD thd, const MYSQL_LEX_STRING db) |
typedef void(* mysql_start_thread_t) (MYSQL_THD thd, void *(*callback_fun)(void *), void *arg, struct my_thread_handle *thread_handle) |
typedef int(* mysql_visit_tree_t) (MYSQL_THD thd, parse_node_visit_function processor, unsigned char *arg) |
Walks the tree depth first and applies a user defined function on each literal.
thd | The session in which the query was parsed. |
processor | Will be called for each literal in the parse tree. |
arg | Will be passed as argument to each call to 'processor'. |
