方法详细资料

getSqlTypeQuotes

public static String getSqlTypeQuotes(SqlDialect sqlDialect)

根据 SQL 方言返回用于表名和列名的合适包裹符号。 不同的 SQL 方言使用不同的符号来包裹标识符（例如，表名或列名）。

参数:

sqlDialect - SQL 方言（例如，MYSQL、ORACLE、POSTGRESQL 等）

返回:

指定 SQL 方言所使用的包裹符号字符串

quoteIdentifier

public static String quoteIdentifier(SqlDialect sqlDialect,
                                     String identifier)

根据 SQL 方言和给定的标识符返回包裹好的标识符。

参数:

sqlDialect - SQL 方言（例如，MYSQL、ORACLE、POSTGRESQL 等）

identifier - 要包裹的标识符（例如，表名或列名）

返回:

包裹好的标识符字符串

                                           TableMeta tableMeta)

按照当前SQL语义匹配最佳表别名

参数:
