public Class SybaseDialect

Overrides org.hibernate.dialect.Dialect.buildIdentifierHelper.

Doc from org.hibernate.dialect.Dialect.buildIdentifierHelper.

Build the IdentifierHelper indicated by this Dialect for handling identifier conversions. Returning null is allowed and indicates that Hibernate should fallback to building a "standard" helper. In the fallback path, any changes made to the IdentifierHelperBuilder during this call will still be incorporated into the built IdentifierHelper.

The incoming builder will have the following set:

• IdentifierHelperBuilder#isGloballyQuoteIdentifiers()
• IdentifierHelperBuilder#getUnquotedCaseStrategy() - initialized to UPPER
• IdentifierHelperBuilder#getQuotedCaseStrategy() - initialized to MIXED

By default Hibernate will do the following:

• Call IdentifierHelperBuilder#applyIdentifierCasing(DatabaseMetaData)
• Call IdentifierHelperBuilder#applyReservedWords(DatabaseMetaData)
• Applies AnsiSqlKeywords#sql2003() as reserved words
• Applies the {#link #sqlKeywords} collected here as reserved words
• Applies the Dialect's NameQualifierSupport, if it defines one

Parameters

builder:IdentifierHelperBuilder

A semi-configured IdentifierHelper builder.

dbMetaData:DatabaseMetaData

Access to the metadata returned from the driver if needed and if available.

Warning

may be null

Returns:IdentifierHelper

The IdentifierHelper instance to use, or null to indicate Hibernate should use its fallback path

Overrides org.hibernate.dialect.Dialect.getInExpressionCountLimit.
