Initializes a new instance of the SybaseASA10Dialect class

Provided we SupportsInsertSelectIdentity, then attch the "select identity" clause to the insert statement.

Some dialects support an alternative means to SELECT FOR UPDATE, whereby a "lock hint" is appends to the table name in the from clause.

Determines whether the specified Object is equal to the current Object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Generate a temporary table name given the bas table.

The syntax used to add a foreign key constraint to a table. If SupportsForeignKeyConstraintInAlterTable is false, the returned string will be added to the create table statement instead. In this case, extra strings, like "add", that apply when using alter table should be omitted.

The syntax that is used to close the if for a constraint exists check, used for dialects that requires begin/end for ifs

Generates a string to limit the result set to a number of maximum results with a specified offset into the results. Expects any database-specific offset and limit adjustments to have already been performed (ex. UseMaxForLimit, OffsetStartsAtOne). Performs error checking based on the various dialect limit support options. If both parameters and fixed valeus are specified, this will use the parameter option if possible. Otherwise, it will fall back to a fixed string.

Some databases require that a limit statement contain the maximum row number instead of the number of rows to retrieve. This method adjusts source limit and offset values to account for this.

Get a strategy instance which knows how to acquire a database-level lock of the specified mode for this dialect.

Gets the name of the longest registered type for a particular DbType.

Some databases use limit row offsets that start at one instead of zero. This method adjusts a desired offset using the OffsetStartsAtOne flag.

Get the name of the database type associated with the given SqlType.

Checks to see if the name has been quoted.

Creates a shallow copy of the current Object.

Does the dialect require that temporary table DDL statements occur in isolation from other statements? This would be the case if the creation would cause any current transaction to get committed implicitly.

For the underlying database, is REPEATABLE_READ isolation implemented by forcing writers to wait for read locks to be released?

ASA does not require to drop constraint before dropping tables, and DROP statement syntax used by Hibernate to drop constraint is not compatible with ASA, so disable it. Comments matchs SybaseAnywhereDialect from Hibernate-3.1 src

Only needed if the Dialect does not have SupportsForeignKeyConstraintInAlterTable.

Retrieves the FOR UPDATE NOWAIT syntax specific to this dialect

Is FOR UPDATE OF syntax supported?

Aggregate SQL functions as defined in general. This is a case-insensitive hashtable!

Set this to false if no table-level primary key constraint should be generated when an identity column has been specified for the table. This is used as a work-around for SQLite so it doesn't tell us we have "more than one primary key".

Whether this dialect has an identity clause added to the data type or a completely separate identity data type.

The keyword used to insert a generated value into an identity column (or null). Need if the dialect does not support inserts that specify no column values.

The class (which implements IIdentifierGenerator) which acts as this dialects identity-style generation strategy.

Should the value returned by CurrentTimestampSelectString be treated as callable. Typically this indicates that JDBC escape sytnax is being used...

The name of the SQL function that transforms a string to lowercase

The class (which implements IIdentifierGenerator) which acts as this dialects native generation strategy.

The opening quote for a quoted identifier.

The keyword used to create a primary key constraint

Get the select command used retrieve the names of all sequences.

Get the command used to select a GUID from the underlying database. (Optional operation.)

Does this dialect support using a JDBC bind parameter as an argument to a function or procedure call?

Does this dialect support definition of cascade delete constraints which can cause circular chains?

Does this dialect support column-level check constraints?

Does this dialect support a way to retrieve the database's current timestamp value?

Does this dialect support empty IN lists? For example, is [where XYZ in ()] a supported construct?

Does the dialect support an exists statement in the select clause?

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...

Does this dialect support adding foreign key constraints via alter table? If not, it's assumed they can only be added through create table.

Does the dialect support the syntax 'drop table NAME if exists'

Does the dialect support the syntax 'drop table if exists NAME'

Does the dialect support some form of inserting and selecting the generated IDENTITY value all in the same statement.

Does this Dialect support an offset?

Does the dialect support propagating changes to LOB values back to the database? Talking about mutating the internal value of the locator as opposed to supplying a new locator instance...

For BLOBs, the internal value might be changed by: {@link java.sql.Blob#setBinaryStream}, {@link java.sql.Blob#setBytes(long, byte[])}, {@link java.sql.Blob#setBytes(long, byte[], int, int)}, or {@link java.sql.Blob#truncate(long)}.

For CLOBs, the internal value might be changed by: {@link java.sql.Clob#setAsciiStream(long)}, {@link java.sql.Clob#setCharacterStream(long)}, {@link java.sql.Clob#setString(long, String)}, {@link java.sql.Clob#setString(long, String, int, int)}, or {@link java.sql.Clob#truncate(long)}.

NOTE : I do not know the correct answer currently for databases which (1) are not part of the cruise control process or (2) do not {@link #supportsExpectedLobUsagePattern}.

Does this dialect support FOR UPDATE in conjunction with outer joined rows?

Does this dialect support parameters within the select clause of INSERT ... SELECT ... statements?

Does this dialect support "pooled" sequences. Not aware of a better name for this. Essentially can we specify the initial and increment values?

Does this dialect support asking the result set its positioning information on forward only cursors. Specifically, in the case of scrolling fetches, Hibernate needs to use {@link java.sql.ResultSet#isAfterLast} and {@link java.sql.ResultSet#isBeforeFirst}. Certain drivers do not allow access to these methods for forward only cursors.

NOTE : this is highly driver dependent!

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') ...".

If the dialect supports {@link #supportsRowValueConstructorSyntax() row values}, does it offer such support in IN lists as well?

For example, "... where (FIRST_NAME, LAST_NAME) IN ( (?, ?), (?, ?) ) ..."

Does this dialect support sequences?

Supports splitting batches using GO T-SQL command

Does this dialect support referencing the table being mutated in a subquery. The "table being mutated" is the table referenced in an UPDATE or a DELETE query. And so can that table then be referenced in a subquery of said UPDATE/DELETE query.

For example, would the following two syntaxes be supported:

• delete from TABLE_A where ID not in ( select ID from TABLE_A )
• update TABLE_A set NON_ID = 'something' where ID in ( select ID from TABLE_A)

Are subselects supported as the left-hand-side (LHS) of IN-predicates.

In other words, is syntax like "... {subquery} IN (1, 2, 3) ..." supported?

Does this dialect support subselects?

Does this dialect support table-level check constraints?

Does this dialect support temporary tables?

Is it supported to materialize a LOB locator outside the transaction in which it was created?

Again, part of the trickiness here is the fact that this is largely driver dependent.

NOTE: all database I have tested which {@link #supportsExpectedLobUsagePattern()} also support the ability to materialize a LOB outside the owning transaction...

Does this dialect support UNION ALL, which is generally a faster variant of UNION? True if UNION ALL is supported; false otherwise.

Does this dialect support the UNIQUE column syntax?

Does this dialect support adding Unique constraints via create and alter table ?

Gives the best resolution that the database can use for storing date/time values, in ticks.

Should LOBs (both BLOB and CLOB) be bound using stream operations (i.e. {@link java.sql.PreparedStatement#setBinaryStream}).

Does the LIMIT clause take a "maximum" row number instead of a total number of returned rows?
