Parsing consists of removing empty (which includes just whitespaces and/or control characters) statements and EOL (end-of-line) comments. However, there's a caveat, by rule, the last EOL comment found in the stream isn't removed if and only if it's the last statement. Why? EOL comments do not generate results, however, when the last statement is an EOL comment the server returns an empty result. So, in other to match statements and results correctly we need to keep the last EOL comment statement. Args: multi_stmt: Query representing multi-statement operations separated by semicolons. Returns: A list of statements that aren't empty and don't contain leading ASCII whitespaces. Also, they aren't EOL comments except perhaps for the last one. � r r )r �RE_SQL_SPLIT_STMTS�splitr1 �popleft�lstripr8 �append)r9 � executed_listr* Znum_stmsZ stmt_nextr6 r6 r7 �parse_multi_statement_query� s rA c @ sB e Zd ZdZddd�dd�Zddd �d d �Zed d �dd��ZdS )�_ParamSubstitutorz4 Substitutes parameters into SQL statement. zSequence[bytes]�None��paramsr+ c C s || _ d| _d S �Nr )rE �index)�selfrE r6 r6 r7 �__init__� s z_ParamSubstitutor.__init__�re.Matchr( ��matchobjr+ c C sF | j }| j d7 _ zt| j| �W S ty@ td�d �Y n0 d S )Nr z+Not enough parameters for the SQL statement)rG r( rE � IndexErrorr )rH rL rG r6 r6 r7 �__call__� s ��z_ParamSubstitutor.__call__�int�r+ c C s t | j�| j S )z8Returns number of parameters remaining to be substituted)r1 rE rG �rH r6 r6 r7 � remaining� s z_ParamSubstitutor.remainingN)�__name__� __module__� __qualname__�__doc__rI rN �propertyrR r6 r6 r6 r7 rB � s rB zDict[bytes, bytes])�bytestr� value_dictr+ c s$ ddd�� fdd� }t �|| �}|S )ah >>> _bytestr_format_dict(b'%(a)s', {b'a': b'foobar'}) b'foobar >>> _bytestr_format_dict(b'%%(a)s', {b'a': b'foobar'}) b'%%(a)s' >>> _bytestr_format_dict(b'%%%(a)s', {b'a': b'foobar'}) b'%%foobar' >>> _bytestr_format_dict(b'%(x)s %(y)s', ... {b'x': b'x=%(y)s', b'y': b'y=%(x)s'}) b'x=%(y)s y=%(x)s' rJ r( rK c sV d}| � � }|d dkr d}|d dkr8|d }� | }|du rRtd|d � ���|S )zReplace pattern.NZconversion_type� %� sZ mapping_keyz Unsupported conversion_type: )� groupdict� ValueError)rL �value�groups�key�rY r6 r7 �replace� s �z%_bytestr_format_dict.<locals>.replace)�RE_PY_MAPPING_PARAM�sub)rX rY rb r* r6 ra r7 �_bytestr_format_dict� s re c s" e Zd ZU dZdZded< dd�� fdd� Zd=d d d d �dd�Zdd�dd�Zd>d dddd�dd�Z d ddd�dd�Z dd�d d �Z d?d d d!�d"d#�Z d d�d$d%�Z d&d�d'd(�Zd)d�d*d+�Zd,d)d-�d.d/�Zd@d,d,d)d1�d2d3�ZdAddd5�d6d7�Zed8d�d9d:��Zed d�d;d<��Z� ZS )B� CursorBasez� Base for defining MySQLCursor.

It matches the given `query_iter` (result of `MySQLConnection.cmd_query_iter()`) and the list of statements that were executed. How does this method work? To properly map each statement (stmt) to a result, the following facts must be considered: 1. Read operations such as `SELECT` produce a non-empty result (calling `next(query_iter)` gets a result that includes at least one column). 2. Write operatios such as `INSERT` produce an empty result (calling `next(query_iter)` gets a result with no columns - aka empty). 3. End-of-line (EOL) comments do not produce a result, unless is the last stmt in which case produces an empty result. 4. Calling procedures such as `CALL my_proc` produce a sequence `(1)*0` which means it may produce zero or more non-empty results followed by just one empty result. In other words, a callproc stmt always terminates with an empty result. E.g., `my_proc` includes an update + select + select + update, then the result sequence will be `110` - note how the write ops results get annulated, just the read ops results are produced. Other examples: * insert + insert -> 0 * select + select + insert + select -> 1110 * select -> 10 Observe how 0 indicates the end of the result sequence. This property is vital to know what result corresponds to what callproc stmt. In this regard, the implementation is composed of: 1. Parsing: the multi-statement is broken down into single statements, and then for each of these, leading white spaces are removed (including jumping line, vertical line, tab, etc.). Also, EOL comments are removed from the stream, except when the comment is the last statement of the multi-statement string. 2. Mapping: the facts described above as used as "game rules" to properly match statements and results. In case, if we run out of statements before running out of results we use a sentinel named "stmt_overflow!" to indicate that the mapping went wrong.

Coding Example: 1) Defining the Stored Routine in MySQL: CREATE PROCEDURE multiply(IN pFac1 INT, IN pFac2 INT, OUT pProd INT) BEGIN SET pProd := pFac1 * pFac2; END 2) Executing in Python: args = (5, 5, 0) # 0 is to hold pprod cursor.callproc('multiply', args) print(cursor.fetchone()) For OUT and INOUT parameters the user should provide the type of the parameter as well. The argument should be a tuple with first item as the value of the parameter to pass and second argument the type of the argument. In the above example, one can call callproc method like: args = (5, 5, (0, 'INT')) cursor.callproc('multiply', args) The type of the argument given in the tuple will be used by the MySQL CAST function to convert the values in the corresponding MySQL type (See CAST in MySQL Reference for more information) Does not return a value, but a result set will be available when the CALL-statement execute successfully.
