getCreateTempTableSqlPrefix()
|
ValueReadQuery |
getTimestampQuery()
|
protected ExpressionOperator |
greatest()
INTERNAL: Build HSQL equivalent to GREATEST(x, y) HSQL: CASE WHEN x >= y THEN x ELSE y |
protected void |
initializePlatformOperators()
|
boolean |
isAlterSequenceObjectSupported()
|
boolean |
isDynamicSQLRequiredForFunctions()
INTERNAL HSQL has some issues with using parameters on certain functions and relations. |

|
void |
printSQLSelectStatement(org.eclipse.persistence.internal.databaseaccess.DatabaseCall call,
org.eclipse.persistence.internal.expressions.ExpressionSQLPrinter printer,
org.eclipse.persistence.internal.expressions.SQLSelectStatement statement)
Print the pagination SQL using HSQL syntax "SELECT LIMIT |
protected ExpressionOperator |
rightTrim2()
INTERNAL: Build HSQL equivalent to RTRIM(string_exp, character). |
boolean |
shouldUseJDBCOuterJoinSyntax()
JDBC escape syntax for outer joins is not supported (not required). |
boolean |
supportsGlobalTempTables()
|
boolean |
supportsIdentity()
|
boolean |
supportsNestingOuterJoins()
Does not allow nesting outer joins, i.e. each join must be followed by the ON clause. |
boolean |
supportsSequenceObjects()
|
boolean |
supportsUniqueColumns()
HSQL (1.8.1) does not support the UNIQUE key word in a column, but does support unique constraints defined separately. |
static ExpressionOperator |
toNumberOperator()
INTERNAL: Use CONVERT function for toNumber. |
static ExpressionOperator |
trimOperator()
INTERNAL: Use TRIM(FROM ?) |
void |
writeUpdateOriginalFromTempTableSql(java.io.Writer writer,
org.eclipse.persistence.internal.helper.DatabaseTable table,
java.util.Collection pkFields,
java.util.Collection assignedFields)
INTERNAL: HSQL does not allow multiple fields to be set as a list, so each field needs to be set one by one. |
