|
|
| Method Summary | |
|---|---|
String |
appendIdentitySelectToInsert(String insertSQL)
Provided we Dialect.supportsInsertSelectIdentity(), then attch the
"select identity" clause to the insert statement. |
String |
appendLockHint(LockMode mode,
String tableName)
Some dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appends to the table name in the from clause. |
String |
applyLocksToSql(String sql,
Map aliasedLockModes,
Map keyColumnNames)
Modifies the given SQL by applying the appropriate updates for the specified lock modes and key columns. |
boolean |
doesReadCommittedCauseWritersToBlockReaders()
For the underlying database, is READ_COMMITTED isolation implemented by forcing readers to wait for write locks to be released? |
boolean |
doesRepeatableReadCauseReadersToBlockWriters()
For the underlying database, is REPEATABLE_READ isolation implemented by forcing writers to wait for read locks to be released? |
boolean |
dropTemporaryTableAfterUse()
Do we need to drop the temporary table after use? |
String |
generateTemporaryTableName(String baseTableName)
Generate a temporary table name given the bas table. |
String |
getAddColumnString()
The syntax used to add a column to a table (optional). |
String |
getCurrentTimestampSelectString()
Retrieve the command used to retrieve the current timestammp from the database. |
String |
getForUpdateString()
Get the string to append to SELECT statements to acquire locks for this dialect. |
String |
getIdentityColumnString()
The syntax used during DDL to define a column as being an IDENTITY. |
String |
getIdentitySelectString()
Get the select command to use to retrieve the last generated IDENTITY value. |
String |
getNullColumnString()
The keyword used to specify a nullable column. |
ResultSet |
getResultSet(CallableStatement ps)
Given a callable statement previously processed by Dialect.registerResultSetOutParameter(java.sql.CallableStatement, int),
extract the ResultSet from the OUT parameter. |
boolean |
isCurrentTimestampSelectStringCallable()
Should the value returned by Dialect.getCurrentTimestampSelectString()
be treated as callable. |
boolean |
qualifyIndexName()
Do we need to qualify index names with the schema name? |
int |
registerResultSetOutParameter(CallableStatement statement,
int col)
Registers an OUT parameter which will be returing a ResultSet. |
boolean |
supportsCurrentTimestampSelection()
Does this dialect support a way to retrieve the database's current timestamp value? |
boolean |
supportsEmptyInList()
Does this dialect support empty IN lists? For example, is [where XYZ in ()] a supported construct? |
boolean |
supportsExistsInSelect()
Does the dialect support an exists statement in the select clause? |
boolean |
supportsIdentityColumns()
Does this dialect support identity column key generation? |
boolean |
supportsInsertSelectIdentity()
Does the dialect support some form of inserting and selecting the generated IDENTITY value all in the same statement. |
boolean |
supportsTemporaryTables()
Does this dialect support temporary tables? |

public String applyLocksToSql(String sql,
Map aliasedLockModes,
Map keyColumnNames)
Dialect
applyLocksToSql in class Dialectsql - the SQL string to modifyaliasedLockModes - a map of lock modes indexed by aliased table names.keyColumnNames - a map of key columns indexed by aliased table names.
public int registerResultSetOutParameter(CallableStatement statement,
int col)

DialectResultSet. How this is accomplished varies greatly
from DB to DB, hence its inclusion (along with Dialect.getResultSet(java.sql.CallableStatement)) here.
registerResultSetOutParameter in class Dialectstatement - The callable statement.col - The bind position at which to register the OUT param.
SQLException - Indicates problems registering the OUT param.
public ResultSet getResultSet(CallableStatement ps)
throws SQLException
DialectDialect.registerResultSetOutParameter(java.sql.CallableStatement, int),
extract the ResultSet from the OUT parameter.
