方法详细资料

processSelectBody

protected void processSelectBody(net.sf.jsqlparser.statement.select.Select selectBody,
 String whereSegment)

andExpression

protected net.sf.jsqlparser.expression.Expression andExpression(net.sf.jsqlparser.schema.Table table,
 net.sf.jsqlparser.expression.Expression where,
 String whereSegment)

delete update 语句 where 处理

processPlainSelect

protected void processPlainSelect(net.sf.jsqlparser.statement.select.PlainSelect plainSelect,
 String whereSegment)

处理 PlainSelect

processWhereSubSelect

protected void processWhereSubSelect(net.sf.jsqlparser.expression.Expression where,
 String whereSegment)

处理where条件内的子查询

支持如下:

1. in
2. =
3. >
4. <
5. >=
6. <=
7. <>
8. EXISTS
9. NOT EXISTS

前提条件: 1. 子查询必须放在小括号中 2. 子查询一般放在比较操作符的右边

参数:

where - where 条件

processSelectItem

protected void processSelectItem(net.sf.jsqlparser.statement.select.SelectItem selectItem,
 String whereSegment)

processFunction

protected void processFunction(net.sf.jsqlparser.expression.Function function,
 String whereSegment)

处理函数

支持: 1. select fun(args..) 2. select fun1(fun2(args..),args..)

fixed gitee pulls/141

参数:

function -

processOtherFromItem

protected void processOtherFromItem(net.sf.jsqlparser.statement.select.FromItem fromItem,
 String whereSegment)

处理子查询等

builderExpression

protected net.sf.jsqlparser.expression.Expression builderExpression(net.sf.jsqlparser.expression.Expression currentExpression,
 List<net.sf.jsqlparser.schema.Table> tables,
 String whereSegment)

处理条件

buildTableExpression

public abstract net.sf.jsqlparser.expression.Expression buildTableExpression(net.sf.jsqlparser.schema.Table table,
 net.sf.jsqlparser.expression.Expression where,
 String whereSegment)

构建数据库表的查询条件

参数:

table - 表对象

where - 当前where条件

whereSegment - 所属Mapper对象全路径

返回:

需要拼接的新条件（不会覆盖原有的where条件，只会在原有条件上再加条件），为 null 则不加入新的条件

toString

public String toString()

覆盖:

toString 在类中 Object

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

canEqual

protected boolean canEqual(Object other)

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object
