How to do an insert with blocks of selects? - mysql

Question

What i'm doing is a simple insert using a select statement to retrieve data from other tables, and here is the problem, i want to do that insert but with multiple inserts trying to imitate a insert with block insertion in fact, if i run the code below it works but just for one row:
INSERT INTO factmonitoreo (idEstacion, IdVariable, IdTiempoRegistro, Valor, ValorOriginal, FlagRegistro)
(SELECT dt.idEstacion, dv.IdVariable, '2007-01-01 00:04:29', 0, 0, 0
FROM dimestacion AS dt
INNER JOIN dimtipoestacion AS dte ON dt.IdTipoEstacion = dte.IdTipoEstacion
JOIN dimvariable AS dv
WHERE dt.Estacion LIKE 'El Lago'
AND dte.CodTipoEstacion LIKE 'ECT'
AND dv.ColumnNameToManualUpdateFromCSV LIKE 'Temperatura')
But if i append a second Select the query doesn't works, see below:
INSERT INTO factmonitoreo (idEstacion, IdVariable, IdTiempoRegistro, Valor, ValorOriginal, FlagRegistro)
(SELECT dt.idEstacion, dv.IdVariable, '2007-01-01 00:04:29', 0, 0, 0
FROM dimestacion AS dt
INNER JOIN dimtipoestacion AS dte ON dt.IdTipoEstacion = dte.IdTipoEstacion
JOIN dimvariable AS dv
WHERE dt.Estacion LIKE 'El Lago'
AND dte.CodTipoEstacion LIKE 'ECT'
AND dv.ColumnNameToManualUpdateFromCSV LIKE 'Temperatura'),
(SELECT dt.idEstacion, dv.IdVariable, '2007-01-01 00:04:28', 0, 0, 0
FROM dimestacion AS dt
INNER JOIN dimtipoestacion AS dte ON dt.IdTipoEstacion = dte.IdTipoEstacion
JOIN dimvariable AS dv
WHERE dt.Estacion LIKE 'El Lago'
AND dte.CodTipoEstacion LIKE 'ECT'
AND dv.ColumnNameToManualUpdateFromCSV LIKE 'Temperatura')
This piece of code raises the following error:
[Code: 1064, SQL State: 42000] You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '
(SELECT dt.idEstacion, dv.IdVariable, '2007-01-01 00:04:28', 0, 0, 0
FROM ...' at line 8 [Script position: 1792 - 1853]
I have read this documentation to do an attempt of insert with multiple selects: 13.2.7.1 INSERT ... SELECT Statement

Answer 1

I don't think it support multiple selects in a single insert statement. just split it into 2 sql, that will be fine...
Look at the About This Manual session,
The ellipsis in SELECT ... context is more like the omission of the statement.
Sometimes ellipsis will indicate the preceding element can be repeated. but usually it will be presented as <element>, [<element>]...
