Database Migration from MySQL to RDM Server - Embedded Tools ...

Migration GuideOverviewThis document gives an overview of the key differences in the SQL implementations between MySQLand RDM Server. It is intended to be a guide for developers to obtain a quick overview of the items totake into consideration when moving an application from MySQL to RDM Server. The first two sectionsof this document outline the differences in the data types and SQL statements that exist between thetwo database solutions. However, it does not outline any of the differences in the native APIs of eachproduct. As long as developers use the standard SQL-API, ODBC and/or JDBC interfaces the matchbetween the two products should be nearly identical. If developers are using the MySQL native C-API atranslation is required to RDM Servers-supported SAG CLI-API. Information on how to do thistranslation can be found at: http://en.wikipedia.org/wiki/Call_Level_Interface.Data TypesThe following table shows the data types supported by MySQL in its data definition language and thecorresponding data types supported by RDM Server when applicable.Data Type MySQL RDM Server8-bit integerBIT16-bit integer SMALLINT SMALLINT24-bit integerMEDIUMINT32-bit integer INT/INTEGER INTEGER64-bit integer BIGINT BIGINT32-bit floating point64-bit floating pointFLOATDOUBLE / REALVariable floating point DECIMAL / NUMERIC DECIMAL / NUMERICDate DATE DATETime TIME TIMEDate and Time DATETIME / TIMESTAMP TIMESTAMPYearYEARCharacter String CHAR / VARCHAR CHAR / VARCHARBinary BINARY / VARBINARY BINARY / VARBINARYhttp://www.raima.comPage | 4
