addConditon

public Children addConditon(boolean condition,
                            boolean ifNull,

getJoinSql

public String getJoinSql()

从类复制的说明: SupportJoinWrapper

获取join SQL语句

覆盖:

getJoinSql 在类中 SupportJoinWrapper<T,String,Children extends SupportJoinChainQueryWrapper<T,Children>>

返回:

构建好的SQL

getConditionR

public String getConditionR(Class<?> entityClass,
                            Field field)

从类复制的说明: SupportJoinWrapper

只为避开类型检查

指定者:

getConditionR 在类中 SupportJoinWrapper<T,String,Children extends SupportJoinChainQueryWrapper<T,Children>>
