1267SQL

MySQL ERROR 1267 (HY000): Illegal mix of collations (utf8mb4_unicode_ci,IMPLICIT) and (utf8mb4_0900_ai_ci,IMPLICIT) for operation '='

Two strings with different collations were compared or joined.

1136SQL

MySQL ERROR 1136 (21S01): Column count doesn't match value count at row 1

An INSERT supplies a different number of values than columns.

ambiguous columnSQL

Column reference is ambiguous / Column 'id' in field list is ambiguous (MySQL 1052)

A column name exists in more than one joined table, so the database doesn’t know which one you mean.

42703PostgreSQL

PostgreSQL: ERROR: column "x" does not exist

PostgreSQL can’t find the column — a missing migration, a case-sensitive quoted name, or a string literal written in double quote…

1064MySQL

MySQL ERROR 1064 (42000): You have an error in your SQL syntax

MySQL couldn’t parse the query. The text after “near” shows where parsing failed.

42601PostgreSQL

ERROR: syntax error at or near "x"

PostgreSQL couldn’t parse the SQL; the token shown is where parsing failed.

1066SQL

MySQL ERROR 1066 (42000): Not unique table/alias: 'x'

The same table or alias appears twice in a FROM/JOIN without distinct aliases.

aggregate in WHERESQL

ERROR: aggregate functions are not allowed in WHERE (use HAVING) / MySQL 1111 Invalid use of group function

An aggregate (SUM, COUNT, AVG) was used in WHERE, which filters rows before grouping.

Two steps away (18)

1366MySQL

MySQL ERROR 1366: Incorrect string value: '\xF0\x9F\x98\x80' for column

The text contains characters (usually emoji) that the column’s character set can’t store — the column or connection is `utf8`/`ut…

1071MySQL

MySQL ERROR 1071 (42000): Specified key was too long; max key length is 767 bytes

An index on a VARCHAR is too long for the row format — classic with utf8mb4 VARCHAR(255) on MySQL 5.6/MariaDB 10.1.

Unknown collationMySQL

MySQL ERROR 1273 (HY000): Unknown collation: 'utf8mb4_0900_ai_ci'

A dump from MySQL 8 uses a collation the target server (MySQL 5.7 / MariaDB) doesn’t support.

GROUP BYSQL

Column must appear in the GROUP BY clause / isn't in GROUP BY (MySQL 1055 only_full_group_by)

You selected a column that is neither grouped nor aggregated, so the result would be ambiguous.

SQLite syntax errorSQL

sqlite3.OperationalError: near "x": syntax error

SQLite couldn’t parse the statement; the token after “near” is where it stopped.

102SQL

SQL Server: Incorrect syntax near 'x'. (Msg 102)

T-SQL couldn’t parse the statement near the shown token.

1054MySQL

MySQL ERROR 1054 (42S22): Unknown column in 'field list'

The query references a column that doesn’t exist in the table (or an unquoted string being read as a column).

ORA-00933SQL

ORA-00933: SQL command not properly ended

Oracle found extra clauses or syntax it doesn’t support at the end of a statement.

window in WHERESQL

ERROR: window functions are not allowed in WHERE

A window function (ROW_NUMBER, RANK, LAG) was filtered directly in WHERE.

42P01PostgreSQL

PostgreSQL: ERROR: relation "x" does not exist

The table/view isn’t found — missing migration, wrong schema, or a case-sensitive quoted name.

23505PostgreSQL

PostgreSQL: ERROR: duplicate key value violates unique constraint

An INSERT/UPDATE would create a duplicate in a UNIQUE or PRIMARY KEY column — or the id sequence is behind the existing data.

42701PostgreSQL

ERROR: column "x" of relation "y" already exists

ALTER TABLE ADD COLUMN for a column that’s already there.

1146MySQL

MySQL ERROR 1146 (42S02): Table 'db.table' doesn't exist

The query references a table that MySQL can’t find in that database.

mysqli_sql_exceptionPHP

Fatal error: Uncaught mysqli_sql_exception

A MySQLi query or connection failed; since PHP 8.1 MySQLi throws exceptions by default.

Parse errorPHP

PHP Parse error: syntax error, unexpected …

PHP can’t parse the file because of a syntax mistake — the real error is often on the line before the one reported.

1248SQL

MySQL ERROR 1248 (42000): Every derived table must have its own alias

A subquery in FROM wasn’t given an alias.

1222SQL

MySQL ERROR 1222 (21000): The used SELECT statements have a different number of columns

The SELECTs combined with UNION return different numbers of columns.

recursion limitSQL

Msg 530: The statement terminated. The maximum recursion 100 has been exhausted before statement completion. / MySQL 3636 Recursive query aborted after 1001 iterations

A recursive CTE exceeded the database’s recursion limit — often an infinite loop in hierarchical data.
