buildVariable

public static Variable buildVariable(int signType,
                                     String all,
                                     String prefix,
                                     String fullKey,
                                     String afterChar)

0.[ID=:ID ] 1.[ID=] 2.[:ID] 3.[ ]
0.[IN(:TYPE)] 1.[IN(] 2.[:TYPE] 3.[)]
0.[= ::SORT ] 1.[=] 2.[::SORT] 3.[ ]
0.[':NM%] 1.['] 2.[:NM] 3.[%]
0.[+ :CODE ] 1.[+] 2.[:CODE] 3.[ ]
0.[+ ::CODE ] 1.[+] 2.[::CODE] 3.[ ]
======================
0.[ID=${ID} ] 1.[ID=] 2.[${ID}] 3.[ ]
0.[IN(${TYPE})] 1.[IN(] 2.[${TYPE}] 3.[)]
0.['${SORT}'] 1.['] 2.[${SORT}] 3.[']
0.['%${NM}%] 1.['%] 2.[${NM}] 3.[%]
0.[CONTAT('%',{CODE}] 1.[CONTAT('%',] 2.[{CODE}] 3.[null]

参数:

signType - 1:以:区分 2:以{}区分

all - all

prefix - prefix CODE = 'A:1' prefix = "A"(因为这个规则，所以只用来解析SQL体不要用来解析查询条件)

fullKey - fullKey

afterChar - afterChar

返回:

Variable
