For example, getting all rows where id is 5: ``` cursor.execute("SELECT * FROM t1 WHERE id = %s", (5,)) ``` If you want each single statement in the script to be related to its corresponding result set, you should enable the `map_results` switch - see workflow example below. If the given script uses `DELIMITER` statements (which are not recognized by MySQL Server), the connector will parse such statements to remove them from the script and substitute delimiters as needed. This pre-processing may cause a performance hit when using long scripts. Note that when enabling `map_results`, the script is expected to use `DELIMITER` statements in order to split the script into multiple query strings. The following characters are currently not supported by the connector in `DELIMITER` statements: `"`, `'`, #`, `/*` and `*/`. If warnings were generated, and `connection.get_warnings` is `True`, then `self.warnings` will be a list containing these warnings. Args: operation: Operation to be executed - it can be a single or a multi statement. params: The parameters found in the tuple or dictionary params are bound to the variables in the operation. Specify variables using `%s` or `%(name)s` parameter style (that is, using format or pyformat style). map_results: It is `False` by default. If `True`, it allows you to know what statement caused what result set - see workflow example below. Only relevant when working with multi statements. Returns: `None`. Example (basic usage): The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation) result_set = await cur.fetchall() # do something with result set ... while (await cur.nextset()): result_set = await cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected. Example (statement-result mapping): The following example runs many single statements in a single go and loads the corresponding result sets sequentially. Additionally, each result set gets related to the statement that caused it: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) # statement 1 is `SET @a=1, @b='2024-02-01'`, # result set from statement 1 is `[]` - aka, an empty set. result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... # 1st call to `nextset()` will laod the result set from statement 2, # statement 2 is `SELECT @a, LENGTH('hello'), @b`, # result set from statement 2 is `[(1, 5, '2024-02-01')]`. # # 2nd call to `nextset()` will laod the result set from statement 3, # statement 3 is `SELECT @@version`, # result set from statement 3 is `[('9.0.0-labs-mrs-8',)]`. # # 3rd call to `nextset()` will return `None` as there are no more sets, # leading to the end of the consumption process of result sets. while (await cur.nextset()): result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... ``` In case the mapping is disabled (`map_results=False`), all result sets get related to the same statement, which is the one provided when calling `execute()`. In other words, the property `statement` will not change as result sets are consumed, which contrasts with the case in which the mapping is enabled. Note that we offer a new fetch-related API command which can be leveraged as a shortcut for consuming result sets - it is equivalent to the previous workflow. ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) async for statement, result_set in cur.fetchsets(): # do something with result set ``` Nrd �ro r� r� r� rd rd re r� I s zMySQLCursorAbstract.executec � s dS )a� Executes the given operation (it can be a multi statement or a MySQL script) substituting any markers with the given parameters. **NOTE: `executemulti()` is deprecated and will be removed in a future release. Use `execute()` instead.** If you want each single statement in the script to be related to its corresponding result set, you should enable the `map_results` switch - see workflow example below. This capability reduces performance. **Unexpected behavior might happen if your script includes the following symbols as delimiters `"`, `'`, `#`, `/*` and `*/`. The use of these should be avoided for now**. Refer to the documentation of `execute()` to see the multi statement execution workflow. Args: operation: Operation to be executed - it can be a single or a multi statement. params: The parameters found in the tuple or dictionary params are bound to the variables in the operation. Specify variables using `%s` or `%(name)s` parameter style (that is, using format or pyformat style). map_results: It is `False` by default.

Returns: A 2-tuple; the first element is the statement that caused the result set, and the second is the result set itself. Example: Consider the following example where multiple statements are executed in one go: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... while (await cur.nextset()): result_set, statement = await cur.fetchall(), cur.statement # do something with result set ... ``` In this case, as an alternative to loading the result sets with `nextset()` in combination with a `while` loop, you can use `fetchsets()` which is equivalent to the previous approach: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation, map_results=True) async for statement, result_set in cur.fetchsets(): # do something with result set ``` N)r� r� r� r6 �nextset)ro Zstatement_cachedZ result_setrd rd re � fetchsets% s$ 4 � �z MySQLCursorAbstract.fetchsetsr� c � s dS )aK Makes the cursor skip to the next available set, discarding any remaining rows from the current set. This method should be used as part of the multi statement execution workflow - see example below. Returns: It returns `None` if there are no more sets. Otherwise, it returns `True` and subsequent calls to the `fetch*()` methods will return rows from the next result set. Example: The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' async with await cnx.cursor() as cur: await cur.execute(sql_operation) result_set = await cur.fetchall() # do something with result set ... while (await cur.nextset()): result_set = await cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected.
