 - bindLimitParametersInReverseOrder
```
public boolean bindLimitParametersInReverseOrder()
```
 Description copied from class: Dialect
 
 ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit. Does this dialect require us to bind the parameters in reverse order?
 
 Overrides:
 
 bindLimitParametersInReverseOrder in class Dialect
 
 Returns:
 
 true if the correct order is limit, offset
 - buildSQLExceptionConversionDelegate
```
public SQLExceptionConversionDelegate buildSQLExceptionConversionDelegate()
```
 Description copied from class: Dialect
 
 Build an instance of a SQLExceptionConversionDelegate for interpreting dialect-specific error or SQLState codes. When Dialect.buildSQLExceptionConverter() returns null, the default SQLExceptionConverter is used to interpret SQLState and error codes. If this method is overridden to return a non-null value, the default SQLExceptionConverter will use the returned SQLExceptionConversionDelegate in addition to the following standard delegates: <ol> <li>a "static" delegate based on the JDBC 4 defined SQLException hierarchy;</li> <li>a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType</li> </ol> It is strongly recommended that specific Dialect implementations override this method, since interpretation of a SQL error is much more accurate when based on the a vendor-specific ErrorCode rather than the SQLState. Specific Dialects may override to return whatever is most appropriate for that vendor.
 
 Overrides:
 
 buildSQLExceptionConversionDelegate in class Dialect
 
 Returns:
 
 The SQLExceptionConversionDelegate for this dialect
 - forUpdateOfColumns

 - getCreateSequenceString
```
public String getCreateSequenceString(String sequenceName)
```
 Description copied from class: Dialect
 
 Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.getCreateSequenceStrings(java.lang.String) to help facilitate that. Dialects which support sequences and can create a sequence in a single command need only override this method. Dialects which support sequences but require multiple commands to create a sequence should instead override Dialect.getCreateSequenceStrings(java.lang.String).
 
 Overrides:
 
 getCreateSequenceString in class Dialect
 
 Parameters:
 
 sequenceName - The name of the sequence
 
 Returns:
 
 The sequence creation command
 - getCreateSequenceString
```
protected String getCreateSequenceString(String sequenceName,
 int initialValue,
 int incrementSize)
 throws MappingException
```
 Description copied from class: Dialect
 
 Overloaded form of Dialect.getCreateSequenceString(String), additionally taking the initial value and increment size to be applied to the sequence definition. The default definition is to suffix Dialect.getCreateSequenceString(String) with the string: " start with {initialValue} increment by {incrementSize}" where {initialValue} and {incrementSize} are replacement placeholders. Generally dialects should only need to override this method if different key phrases are used to apply the allocation information.
 
 Overrides:
 
 getCreateSequenceString in class Dialect
 
 Parameters:
 
 sequenceName - The name of the sequence
 
 initialValue - The initial value to apply to 'create sequence' statement
 
 incrementSize - The increment value to apply to 'create sequence' statement
 
 Returns:
 
 The sequence creation command
 
 Throws:
 
 MappingException - If sequences are not supported.
 - getCurrentTimestampSelectString
```
public String getCurrentTimestampSelectString()
```
 Description copied from class: Dialect
 
 Retrieve the command used to retrieve the current timestamp from the database.
 
 Overrides:
 
 getCurrentTimestampSelectString in class Dialect
 
 Returns:
 
 The command.
 - getDropSequenceString
```
public String getDropSequenceString(String sequenceName)
```
 Description copied from class: Dialect
 
 Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.getDropSequenceStrings(java.lang.String) to help facilitate that. Dialects which support sequences and can drop a sequence in a single command need only override this method. Dialects which support sequences but require multiple commands to drop a sequence should instead override Dialect.getDropSequenceStrings(java.lang.String).
 
 Overrides:
 
 getDropSequenceString in class Dialect
 
 Parameters:
 
 sequenceName - The name of the sequence
 
 Returns:
 
 The sequence drop commands
 - getForUpdateString
```
public String getForUpdateString(String aliases)
```
 Description copied from class: Dialect
 
 Get the <tt>FOR UPDATE OF column_list</tt> fragment appropriate for this dialect given the aliases of the columns to be write locked.
 
 Overrides:
 
 getForUpdateString in class Dialect
 
 Parameters:
 
 aliases - The columns to be write locked.
 
 Returns:
 
 The appropriate <tt>FOR UPDATE OF column_list</tt> clause string.
 - getForUpdateString
```
public String getForUpdateString(String aliases,
 LockOptions lockOptions)
```
 Description copied from class: Dialect
 
 Get the <tt>FOR UPDATE OF column_list</tt> fragment appropriate for this dialect given the aliases of the columns to be write locked.
 
 Overrides:
 
 getForUpdateString in class Dialect

 - getLimitString
```
public String getLimitString(String sql,
 boolean hasOffset)
```
 Description copied from class: Dialect
 
 Apply s limit clause to the query. Typically dialects utilize variable limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest since we will just be using placeholders. Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method and Dialect.getLimitString(String, int, int).
 
 Overrides:
 
 getLimitString in class Dialect
 
 Parameters:
 
 sql - The query to which to apply the limit.
 
 hasOffset - Is the query requesting an offset?
 
 Returns:
 
 the modified SQL
 - getNotExpression

public String getNotExpression(String expression)
```
 Description copied from class: Dialect

 Parameters:
 
 sequenceName - the name of the sequence
 
 Returns:
 
 The "nextval" fragment.
 - getSequenceNextValString

 Generate the appropriate select statement to to retrieve the next value of a sequence. This should be a "stand alone" select statement.
 
 Overrides:
 
 getSequenceNextValString in class Dialect
 
 Parameters:

 Overrides:
 
 isCurrentTimestampSelectStringCallable in class Dialect
 
 Returns:
 
 True if the Dialect.getCurrentTimestampSelectString() return is callable; false otherwise.
 - registerHanaKeywords
```
protected void registerHanaKeywords()

public boolean supportsExpectedLobUsagePattern()
```
 Description copied from class: Dialect
 
 Expected LOB usage pattern is such that I can perform an insert via prepared statement with a parameter binding for a LOB value without crazy casting to JDBC driver implementation-specific classes… Part of the trickiness here is the fact that this is largely driver dependent.

 Does this dialect support "pooled" sequences. Not aware of a better name for this. Essentially can we specify the initial and increment values?
 
 Overrides:
 
 supportsPooledSequences in class Dialect
 
 Returns:
 
 True if such "pooled" sequences are supported; false otherwise.
 
 See Also:

 Overrides:
 
 dropConstraints in class Dialect
 
 Returns:
 
 True if constraints must be dropped prior to dropping the table; false otherwise.
 - supportsRowValueConstructorSyntax
```
public boolean supportsRowValueConstructorSyntax()
```
 Description copied from class: Dialect
 
 Is this dialect known to support what ANSI-SQL terms "row value constructor" syntax; sometimes called tuple syntax. Basically, does it support syntax like "… where (FIRST_NAME, LAST_NAME) = ('Steve', 'Ebersole') …".
 
 Overrides:
 
 supportsRowValueConstructorSyntax in class Dialect
 
 Returns:
 
 True if this SQL dialect is known to support "row value constructor" syntax; false otherwise.
 - supportsRowValueConstructorSyntaxInInList

 Returns:
 
 True if this SQL dialect is known to support "row value constructor" syntax in the IN list; false otherwise.
 - getMaxAliasLength
```
public int getMaxAliasLength()
```
 Description copied from class: Dialect
 
 What is the maximum length Hibernate can use for generated aliases? The maximum here should account for the fact that Hibernate often needs to append "uniqueing" information to the end of generated aliases. That "uniqueing" information will be added to the end of a identifier generated to the length specified here; so be sure to leave some room (generally speaking 5 positions will suffice).
 
 Overrides:
 
 getMaxAliasLength in class Dialect
 
 Returns:
 
 The maximum length.

 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:<ul> <li>IdentifierHelperBuilder.isGloballyQuoteIdentifiers()</li> <li>IdentifierHelperBuilder.getUnquotedCaseStrategy() - initialized to UPPER</li> <li>IdentifierHelperBuilder.getQuotedCaseStrategy() - initialized to MIXED</li> </ul> By default Hibernate will do the following:<ul> <li>Call IdentifierHelperBuilder.applyIdentifierCasing(DatabaseMetaData) <li>Call IdentifierHelperBuilder.applyReservedWords(DatabaseMetaData) <li>Applies AnsiSqlKeywords.sql2003() as reserved words</li> <li>Applies the {#link #sqlKeywords} collected here as reserved words</li> <li>Applies the Dialect’s NameQualifierSupport, if it defines one</li> </ul>
 
 Overrides:
 
 buildIdentifierHelper in class Dialect
 
 Parameters:
 
 builder - A semi-configured IdentifierHelper builder.
 
 dbMetaData - Access to the metadata returned from the driver if needed and if available. WARNING: may be null
 
 Returns:
 
 The IdentifierHelper instance to use, or null to indicate Hibernate should use its fallback path
 
 Throws:
 
 SQLException - Accessing the DatabaseMetaData can throw it. Just re-throw and Hibernate will handle.
