  - 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:
    1. a "static" delegate based on the JDBC 4 defined SQLException hierarchy;
    2. a delegate that interprets SQLState codes for either X/Open or SQL-2003 codes, depending on java.sql.DatabaseMetaData#getSQLStateType
    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

```
    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
  - getDefaultMultiTableBulkIdStrategy

  - 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 FOR UPDATE OF column_list 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 FOR UPDATE OF column_list clause string.
  - getForUpdateString
```
public String getForUpdateString(String aliases,

    Overrides:
    
    getForUpdateString in class Dialect
    
    Parameters:
    
    aliases - The columns to be write locked.
    
    lockOptions - the lock options to apply
    
    Returns:
    
    The appropriate FOR UPDATE OF column_list clause string.
  - 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

```
    Description copied from class: Dialect
    
    Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement.
    This differs from Dialect.getSequenceNextValString(String) in that this should return an expression usable within another statement.
    
    Overrides:
    
    getSelectSequenceNextValString in class Dialect
    
    Parameters:
    
    sequenceName - the name of the sequence
    
    Returns:

    Parameters:
    
    sqlCode - A Types constant indicating the SQL column type
    
    Returns:
    
    The SqlTypeDescriptor to use as an override, or null if there is no override.

    defaultScrollMode in class Dialect
    
    Returns:
    
    ScrollMode

    HANA currently does not support check constraints.
    
    Overrides:
    
    supportsColumnCheck in class Dialect
    
    Returns:
    
    True if column-level CHECK constraints are supported; false otherwise.

    supportsCurrentTimestampSelection in class Dialect
    
    Returns:
    
    True if the current timestamp can be retrieved; false otherwise.
  - supportsEmptyInList
```
public boolean supportsEmptyInList()

    True if exists checks are allowed in the select clause; false otherwise.
  - supportsExpectedLobUsagePattern
```
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. For example, Oracle (which is notoriously bad with LOB support in their drivers historically) actually does a pretty good job with LOB support as of the 10.2.x versions of their drivers...
    
    Overrides:
    
    supportsExpectedLobUsagePattern in class Dialect
    
    Returns:

    Overrides:
    
    supportsUnionAll in class Dialect
    
    Returns:
    
    True if UNION ALL is supported; false otherwise.
  - dropConstraints
```
public boolean dropConstraints()
```
    Description copied from class: Dialect
    
    Do we need to drop constraints before dropping tables in this dialect?
    
    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:

    Description copied from class: Dialect
    
    If the dialect supports row values, does it offer such support in IN lists as well?
    For example, "... where (FIRST_NAME, LAST_NAME) IN ( (?, ?), (?, ?) ) ..."
    
    Overrides:
    
    supportsRowValueConstructorSyntaxInInList in class Dialect
    
    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.

    The default behaviour for 'on update restrict' on HANA is currently to not allow any updates to any column of a row if the row has a foreign key. Make the default for foreign keys have 'on update cascade' to work around the issue.

    getAddForeignKeyConstraintString in class Dialect
    
    Parameters:
    
    constraintName - The FK constraint name.
    
    foreignKey - The names of the columns comprising the FK

    referencesPrimaryKey - if false, constraint should be explicit about which column names the constraint refers to
    
    Returns:
    
    the "add FK" fragment
