Condition	and() 默认自动加 and.
Condition	between(String field, Number low, Number high)
Condition	between(String field, String low, String high)
Condition	groupBy(String field)
Condition	having(FunctionType functionType, String field, Op Op, Number value) eg: having(FunctionType.MIN, "field", Op.ge, 60)-->having min(field)>=60
Condition	having(String expressionStr) eg:having("count(*)>5") --> having count(*)>5
Condition	lParentheses()
Condition	notBetween(String field, Number low, Number high)
Condition	notBetween(String field, String low, String high)
Condition	op(String field, Op Op, Object value)
Condition	or()
Condition	orderBy(FunctionType functionType, String field, OrderType orderType) eg: orderBy(FunctionType.MAX, "total", OrderType.DESC)-->order by max(total) desc
Condition	orderBy(String field)
Condition	orderBy(String field, OrderType orderType)
Condition	rParentheses()
Condition	setIncludeType(IncludeType includeType) 设置IncludeType过滤参数.op,between,notBetween方法设置的字段,不受includeType的值影响.
Condition	size(Integer size)

从接口继承的方法 org.teasoft.bee.osql.ConditionAssistant

getFieldSet, getIncludeType, setSuidType

方法详细资料

start

Condition start(Integer start)

size

Condition size(Integer size)

setIncludeType

Condition setIncludeType(IncludeType includeType)

设置IncludeType过滤参数.op,between,notBetween方法设置的字段,不受includeType的值影响. 如果Condition没有使用该方法设置,则按默认过滤方式处理.

参数:

includeType -

having

Condition having(String expressionStr)

eg:having("count(*)>5") --> having count(*)>5

参数:
