public Sql[]
generateSql(CreateIndexStatement
A CreateIndexStatement with the desired properties of the SQL to be generated
statement, Database
The DBMS for whose SQL dialect the statement is to be made

The other SQL generators in the same chain (but this method is not interested in them)
sqlGeneratorChain)

Overrides liquibase.sqlgenerator.core.CreateIndexGenerator.generateSql.

Implements liquibase.sqlgenerator.SqlGenerator.generateSql.

Generate a CREATE INDEX SQL statement.

public int
getPriority()

Overrides liquibase.sqlgenerator.core.AbstractSqlGenerator.getPriority.

Implements liquibase.sqlgenerator.SqlGenerator.getPriority.

Of all the SqlGenerators that "support" a given SqlStatement/Database, SqlGeneratorFactory will return the one with the highest priority.

public boolean
supports(CreateIndexStatement statement, Database database)

Overrides liquibase.sqlgenerator.core.AbstractSqlGenerator.supports.

Implements liquibase.sqlgenerator.SqlGenerator.supports.

Does this generator support the given statement/database combination?

public Sql[] generateSql(CreateIndexStatement statement, Database database, SqlGeneratorChain<T extends SqlStatement> sqlGeneratorChain)

Overrides liquibase.sqlgenerator.core.CreateIndexGenerator.generateSql.

Implements liquibase.sqlgenerator.SqlGenerator.generateSql.

Doc from liquibase.sqlgenerator.core.CreateIndexGenerator.generateSql.

Generate a CREATE INDEX SQL statement. Here, we are walking on thin ice, because the SQL Foundation standard (ISO/IEC 9075-2) does not concern itself with indexes at all and leaves them as an implementation-specific detail at the discretion of each RDBMS vendor. However, there is some common ground to most RDBMS, and we try to make an educated guess on how a CREATE INDEX statement might look like if we have no specific handler for the DBMS.

Parameters
statement:CreateIndexStatement

A CreateIndexStatement with the desired properties of the SQL to be generated

database:Database

The DBMS for whose SQL dialect the statement is to be made

sqlGeneratorChain:SqlGeneratorChain<T extends SqlStatement>

The other SQL generators in the same chain (but this method is not interested in them)

Returns:Sql[]

An array of Sql objects containing the generated SQL statement(s).

Does this generator support the given statement/database combination? Do not validate the statement with this method, only return if it can support it.
