simpleorm.core.SDriverMSSQL
| SDriverMSSQL | | public class SDriverMSSQL extends SDriver (Code) | | This contains MS SQL Server specific code.
CHAR, VARCHAR max 8,000. TEXT 2^31. NVARCHAR/NCHAR UTF16, max size 4,000.
|
| xLockEnabled | | boolean xLockEnabled(Code) | | |
| columnTypeSQL | | protected String columnTypeSQL(SFieldMeta field)(Code) | | Apparantly need DATETIME instead of TIMESTAMP
|
| forUpdateSQL | | protected String forUpdateSQL(boolean forUpdate)(Code) | | |
| getXLockEnabled | | public boolean getXLockEnabled()(Code) | | |
| postFromSQL | | protected String postFromSQL(boolean forUpdate, boolean unrepeatableRead)(Code) | | XLOCK is not strictly necessary in MS SQL because it does not
provide Oracle-like data versioning.
But having XLOCK should reduce deadlocks. More importantly,
2005 is supposed to be providing data versioning
("Snapshots").
However, Jorge says that it is unnecessary and makes SimpleORM
fail, but it works for me.

See Also: for discussion. |
| setXLockEnabled | | public void setXLockEnabled(boolean xlock)(Code) | | Enables WITH (XLOCK) for updatable queries.
Should reduce deadlocks but apparantly can cause bugs.
(Not supported in SQL 7? Something about HOLDLOCK?)
