fixed the issue. Will look into that further I think the error might be that you have not given a name to your sub query. Please try this -
code :
SELECT StartTerminal, SUM(count) as TotalCount
FROM (
SELECT StartTerminal, COUNT(*) as count
FROM test.2013_q1
GROUP BY StartTerminal
UNION ALL
SELECT StartTerminal, COUNT(*) as count
FROM test.2013_q2
GROUP BY StartTerminal
) all_year_data
GROUP BY StartTerminal;

wish of those help Ultimately to solve this issue I get results from the separate tables and do my loops and comparisons in code. Later, it was made more efficient to combine all the sensor data in one table and optimize said table with indexes, which previously had been missing.
The moral of the story is that proper table structure is key to eliminating a lot of coding headaches!

this one helps. Lets say i have 4 identical tables: table1, table2, table3, table4
code :
(SELECT * FROM table1 where date = '2011-06-23')
UNION
(SELECT * FROM table2 where date = '2011-06-23')
UNION    
(SELECT * FROM table3 where date = '2011-06-23')
UNION    
(SELECT * FROM table4 where date = '2011-06-23')

around this issue I have multiple tables with identical columns and different data in them and i'm trying to make a single query to pull the data from all those tables and treat them as a single query. I also need to know from which table is the specific result. I found this to help me get a query from multiple tables, but when i try , You can do by this way
code :
foreach ($tables as $table) {
  $table = '`'.mb_ereg_replace('`','``',$table).'`';
  $sql[] = "(
    SELECT   *,'".$table."' AS tableName
    FROM  $table
    ORDER BY status
    LIMIT    50
  )";
}

To fix this issue I am in need of some help with mysql since I'm a novice with it. I need to count the values of different tables from different databases and put them all in one table, after that make an index for each count, for example: , Try this.
code :
SELECT "db1.tb1" as "INDEXES", COUNT(*) AS "COUNTS" FROM `db1`.`tb1`
UNION
SELECT "db2.tb2" as "INDEXES", COUNT(*) AS "COUNTS" FROM `db2`.`tb2`

it helps some times Well, the solution after some fiddling with the "", '' and `` characters is as such:
code :
SELECT
SUM(`Keine Operation durchgeführt`) AS `No surgery`,
SUM(`Bioenterics Intragastric Ballon (BIB)`) AS `BIB`,
SUM(`Gastric Banding`) AS `GB`,
SUM(`Roux-en-Y Gastric Bypass`) AS `RYGB`,
SUM(`Anderes OP-Verfahren`) AS `Other Surgery`,
SUM(`Summe`) AS `Total`

FROM
(

    SELECT
    COUNT(IF(op.OP1OPVerfahren = 0, 1, NULL)) AS `Keine Operation durchgeführt`,
    SUM(op.OP1OPVerfahren = 1) AS `Bioenterics Intragastric Ballon (BIB)`,
    SUM(op.OP1OPVerfahren = 2) AS `Gastric Banding`,
    SUM(op.OP1OPVerfahren = 3) AS `Roux-en-Y Gastric Bypass`,
    SUM(op.OP1OPVerfahren = 99) AS `Anderes OP-Verfahren`,
    SUM(op.OP1OPVerfahren LIKE '%') AS `Summe`

    FROM ods01.dat_patient p
    LEFT OUTER JOIN ods01.dat_optherapie op ON op.patID = p.ID

    WHERE op.OP1Datum BETWEEN '1950-01-01' AND '2019-12-31'
    AND p.Testzwecke = 0
    AND NOT EXISTS (SELECT 1
        FROM ods01.dat_optherapie op2
        WHERE op2.patID = p.ID AND op2.revision > op.revision
    )

    UNION ALL

    SELECT
    COUNT(IF(op.OP1OPVerfahren = 0, 1, NULL)) AS `Keine Operation durchgeführt`,
    SUM(op.OP1OPVerfahren = 1) AS `Bioenterics Intragastric Ballon (BIB)`,
    SUM(op.OP1OPVerfahren = 2) AS `Gastric Banding`,
    SUM(op.OP1OPVerfahren = 3) AS `Roux-en-Y Gastric Bypass`,
    SUM(op.OP1OPVerfahren = 99) AS `Anderes OP-Verfahren`,
    SUM(op.OP1OPVerfahren LIKE '%') AS `Summe`

    FROM ods02.dat_patient p
    LEFT OUTER JOIN ods02.dat_optherapie op ON op.patID = p.ID

    WHERE op.OP1Datum BETWEEN '1950-01-01' AND '2019-12-31'
    AND p.Testzwecke = 0
    AND NOT EXISTS (SELECT 1
        FROM ods02.dat_optherapie op2
        WHERE op2.patID = p.ID AND op2.revision > op.revision
    )

    UNION ALL

    SELECT
    COUNT(IF(op.OP1OPVerfahren = 0, 1, NULL)) AS `Keine Operation durchgeführt`,
    SUM(op.OP1OPVerfahren = 1) AS `Bioenterics Intragastric Ballon (BIB)`,
    SUM(op.OP1OPVerfahren = 2) AS `Gastric Banding`,
    SUM(op.OP1OPVerfahren = 3) AS `Roux-en-Y Gastric Bypass`,
    SUM(op.OP1OPVerfahren = 99) AS `Anderes OP-Verfahren`,
    SUM(op.OP1OPVerfahren LIKE '%') AS `Summe`

    FROM ods03.dat_patient p
    LEFT OUTER JOIN ods03.dat_optherapie op ON op.patID = p.ID

    WHERE op.OP1Datum BETWEEN '1950-01-01' AND '2019-12-31'
    AND p.Testzwecke = 0
    AND NOT EXISTS (SELECT 1
        FROM ods03.dat_optherapie op2
        WHERE op2.patID = p.ID AND op2.revision > op.revision
    )

) whatever;
