INTERNAL:
HSQL requires START WITH first.

computeMaxRowsForSQL(int firstResultIndex,
int maxResults)
INTERNAL:
Use the JDBC maxResults and firstResultIndex setting to compute a value to use when
limiting the results of a query in SQL.

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.
