| db_status_report($phase) X-Ref |
| Report database status. |
| db_version() X-Ref |
| Returns the version of the database server currently in use. return: Database server version |
| db_connect($url) X-Ref |
| Initialise a database connection. Note that mysqli does not support persistent connections. |
| _db_query($query, $debug = 0) X-Ref |
| Helper function for db_query(). |
| db_fetch_object($result) X-Ref |
| Fetch one result row from the previous query as an object. param: $result return: |
| db_fetch_array($result) X-Ref |
| Fetch one result row from the previous query as an array. param: $result return: |
| db_num_rows($result) X-Ref |
| Determine how many result rows were found by the preceding query. param: $result return: |
| db_result($result, $row = 0) X-Ref |
| Return an individual result field from the previous query. Only use this function if exactly one field is being selected; otherwise, use db_fetch_object() or db_fetch_array(). param: $result param: $row return: |
| db_error() X-Ref |
| Determine whether the previous query caused an error. |
| db_next_id($name) X-Ref |
| Return a new unique ID in the given sequence. For compatibility reasons, Drupal does not use auto-numbered fields in its database tables. Instead, this function is used to return a new unique ID of the type requested. If necessary, a new sequence with the given name will be created. Note that the table name should be in curly brackets to preserve compatibility with table prefixes. For example, db_next_id('{node}_nid'); |
| db_affected_rows() X-Ref |
| Determine the number of rows changed by the preceding query. |
| db_query_range($query) X-Ref |
| Runs a limited-range query in the active database. Use this as a substitute for db_query() when a subset of the query is to be returned. User-supplied arguments to the query should be passed in as separate parameters so that they can be properly escaped to avoid SQL injection attacks. param: $query param: ... param: $from param: $count return: |
| db_query_temporary($query) X-Ref |
| Runs a SELECT query and stores its results in a temporary table. Use this as a substitute for db_query() when the results need to stored in a temporary table. Temporary tables exist for the duration of the page request. User-supplied arguments to the query should be passed in as separate parameters so that they can be properly escaped to avoid SQL injection attacks. Note that if you need to know how many results were returned, you should do a SELECT COUNT(*) on the temporary table afterwards. db_num_rows() and db_affected_rows() do not give consistent result across different database types in this case. param: $query param: ... param: $table return: |
| db_encode_blob($data) X-Ref |
| Returns a properly formatted Binary Large Object value. param: $data return: |
| db_decode_blob($data) X-Ref |
| Returns text from a Binary Large OBject value. param: $data return: |
| db_escape_string($text) X-Ref |
| Prepare user input for use in a database query, preventing SQL injection attacks. |
| db_lock_table($table) X-Ref |
| Lock a table. |
| db_unlock_tables() X-Ref |
| Unlock all locked tables. |
| db_table_exists($table) X-Ref |
| Check if a table exists. |
| db_distinct_field($table, $field, $query) X-Ref |
| Wraps the given table.field entry with a DISTINCT(). The wrapper is added to the SELECT list entry of the given query and the resulting query is returned. This function only applies the wrapper if a DISTINCT doesn't already exist in the query. param: $table Table containing the field to set as DISTINCT param: $field Field to set as DISTINCT param: $query Query to apply the wrapper to return: SQL query with the DISTINCT wrapper surrounding the given table.field. |
