“ROWID table splitting CANNOT be used if the target database is a non-Oracle database”. Technically, the R3load dump files are independent of database and operating system. There's one restriction, however, restart of a package during import isn't possible on SQL Server. ...
Run-time data is provided in one of the two ways: You can define a callback using the OCIBindDynamic() function which when called at run time returns a piece or the whole data. If no callbacks are defined, the call to OCIStmtExecute() to process the SQL statement returns the OCI_...
The "DBMS_COMPRESSION" PL/SQL package (commonly called compression advisor) gathers compression-related information within a database environment. This includes estimating the compressibility of both uncompressed partitioned, and non- partitioned tables, and gathering row-level compression information on ...
This article describes the frequently asked questions about the advanced SQL Server options that are used to integrate the Active Directory domain password policies with Microsoft Dynamics GP.
The “DBMS_COMPRESSION” PL/SQL package (commonly called compression advisor) is included with Oracle Database Enterprise Edition and gathers compression-related information within a database environment.
