当我想成为此查询时:
Documentos.select("estaciones, 1 as totalPruebas, 1 as totalFilas, 1 as totalPreguntas, '' as nombreColegio").where("id = #{idUsuario}").order("estaciones")
我得到了以下结果:
PG :: SyntaxError:错误:沿“ as”行的错误代码第1行: SELECT COUNT(estaciones,1作为totalPruebas,1作为totalFila ... ^
: SELECT COUNT(estaciones, 1 as totalPruebas, 1 as totalFilas, 1 as totalPreguntas, '' as nombreColegio") FROM "documentos"
答案 0 :(得分:0)
当我想使用“ as”重命名列时,添加一个计数,但是我只是Terminales.select(“ estaciones as nombreEstacion”)
PG :: SyntaxError:错误:语法错误“ as» 第1行:SELECT COUNT(终端。,测试为estasion)AS count_termin ... ^ :选择COUNT(terminales。,测试为estasion)。AS count_terminales_all_estacion_as_test,“ terminales”。“ id” AS terminales_id来自“ terminales” GROUP BY“ terminales”。“ id”
谢谢!
