命令不同步;你現在不能運行這個

Question

我正在SELECT子句中使用子查詢對mysql進行查詢，並且出現此錯誤：＃2014 - 命令不同步;你現在不能運行這個命令 我還沒有能夠解決它。你能幫我嗎？

SELECT e.IdDocumento, e.CveDistrito, d.STCT_NOM, e.CveJuzgado, j.CTJU_DESCR, e.NumDocumento, e.IdRamoDocumento, r.Descripcion....., (SELECT pd.nombre FROM ParteDocumento AS pd WHERE pd.IdDocumento = e.IdDocumento) AS NombreActor 
FROM Documentos AS e 
INNER JOIN CtRamo AS r ON (r.IdRamo = e.IdRamoDocumento) 
INNER JOIN CtEstado AS edo ON (edo.CveEstado = e.CveEstado) 
INNER JOIN CTDISJUD AS d ON (d.STCT_NUM = e.CveDistrito) 
INNER JOIN CTJUZGAD AS j ON (j.CTJU_MUNIC = e.CveDistrito AND j.CTJU_JUZGA = e.CveJuzgado) 
LEFT JOIN CtMedioPresentacion AS m ON (m.IdMedioPresentacion = e.IdMedioPresentacion) 
WHERE e.IdTipoDocumento =1 AND e.EsRecibido =1 

這是我的查詢。我在SQL Server中做了同樣的查詢，它的工作原理！

我不是100％確定的，但我認爲你不能在select的子查詢中使用來自from子句的表。但爲什麼不簡單地加入表而不是子查詢：

SELECT e.IdDocumento, e.CveDistrito, d.STCT_NOM, e.CveJuzgado, j.CTJU_DESCR, e.NumDocumento, e.IdRamoDocumento, r.Descripcion....., pd.nombreNombreActor 
FROM Documentos AS e 
INNER JOIN CtRamo AS r ON (r.IdRamo = e.IdRamoDocumento) 
INNER JOIN CtEstado AS edo ON (edo.CveEstado = e.CveEstado) 
INNER JOIN CTDISJUD AS d ON (d.STCT_NUM = e.CveDistrito) 
INNER JOIN CTJUZGAD AS j ON (j.CTJU_MUNIC = e.CveDistrito AND j.CTJU_JUZGA = e.CveJuzgado) 
LEFT JOIN CtMedioPresentacion AS m ON (m.IdMedioPresentacion = e.IdMedioPresentacion) 
LEFT JOIN ParteDocumento as pd on pd.IdDocumento = e.IdDocumento 
WHERE e.IdTipoDocumento =1 AND e.EsRecibido =1
