The drivers and Driver Manager must make these conversions; Unicode data in a database can be accessed only by W function calls, and ANSI data can only be accessed by standard, non-W function calls. This determination is made by checking two ODBC environment attributes: The driver returns argument values to the Driver Manager.
UCS-2 encoding is a fixed, two-byte encoding sequence and is mjsql method for transforming Unicode values into byte sequences.
Software developers have used a number of character encodings, from ASCII to Unicode, to solve the many problems that arise when developing software applications that can be used worldwide.
The extension, known as the Double-Byte Character Set DBCSallowed existing applications to function without change, but provided for the use of additional characters, including odbf Asian characters. As a result, several kdbc transliterations were designed to convert two-byte fixed Unicode values into more appropriate character encodings, including, among others, UTF-8, UCS-2, and UTF Using the eighth bit to extend the total range of characters to added support for most European characters.
On Windows, this reference is to the Active Code Page. A consistent implementation of Unicode not only depends on the operating system, but also on the database itself.
He may be referring to:. The way in which a driver handles function calls from a Unicode application determines whether it is called a “Unicode driver.
MySQL Connector/ODBC has been released |
This is done as follows: Post as a guest Name. An operation involving a Unicode application and a non-Unicode driver incurs more overhead because function conversion is involved.
Unicode Application with a Unicode Driver An operation involving a Unicode application and a Unicode driver that use the same Unicode encoding is more efficient because no unicods conversion is involved.
If neither of the preceding attempts are successful, the Driver Manager assumes that the Unicode encoding of the driver is UTF This attribute determines how character data is converted and presented to an application and the database. As the need increased for applications with additional international support, ANSI again increased the functionality of ASCII by developing an extension to accommodate multilingual software.

Understanding Unicode and ODBC Data Access
Determine the application Unicode type: The Driver Manager assumes that myxql Unicode encoding of the driver corresponds to the value specified. Add the following line at the very beginning of applications that use double-byte character sets: Services Consulting Education Modernization Outsourcing.
The Driver Manager passes Unicode function calls to the Unicode driver. Based on the information it has gathered prior to connection, the Driver Manager either does not have to convert function calls, or, before calling the driver, it converts to either UTF-8 or UTF all string arguments to calls to the ODBC “W” functions.
If not, conversion errors are possible.
