What is new in this release:

• The new connection option can_handle_exp_pwd indicates that your application includes error-handling logic to deal with the error code for an expired password.

What is new in version 5.1.11:

• A new connection option, prefetch, allows applications to scroll through large query result sets, N records at a time.

What is new in version 5.1.8:

• Functionality added or changed:
• Documentation in .CHM and .HLP format has been removed from the distribution.
• Bugs fixed:
• For some procedure and parameter combinations SQLProcedureColumns() did not work correctly. For example, it could not return records for an existing procedure with correct parameters supplied. Further, it returned incorrect data for column 7, TYPE_NAME. For example, it returned VARCHAR(20) instead of VARCHAR.
• The MySQL Connector/ODBC MSI installer did not set the InstallLocation value in the Microsoft Windows registry.
• In bulk upload mode, SQLExecute would return SQL_SUCCESS, even when the uploaded data contained errors, such as primary key duplication, and foreign key violation.
• SQLDescribeCol and SQLColAttribute could not be called before SQLExecute, if the query was parameterized and not all parameters were bound.
• When SQLNumResultCols() was called between SQLPrepare() and SQLExecute() the driver ran SET @@sql_select_limit=1, which limited the resultset to just one row.
• After installing MySQL Connector/ODBC, the system DSN created could not be configured or deleted. An error dialog was displayed, showing the error message "Invalid attribute string".
• When used after a call to SQLTables(), SQLRowCount() did not return the correct value.

What is new in version 5.1.7:

• Functionality added or changed:
• MySQL Connector/ODBC has been changed to support the CLIENT_INTERACTIVE flag.
• Bugs fixed:
• SQLColAttribute for SQL_DESC_OCTET_LENGTH returned length including terminating null byte. It should not have included the null byte.
• The SQLColumns function returned the incorrect transfer octet length into the column BUFFER_LENGTH for DECIMAL type.
• SQLForeignKeys() did not return the correct information. The list of foreign keys in other tables should not have included foreign keys that point to unique constraints in the specified table.
