Code Inspections in SQL
Inspection | Description | Default Severity |
---|---|---|
Unresolved reference | This inspection performs unresolved SQL references check. | |
Types compatibility | This inspection performs type-related check. | |
Unused variable | This inspection performs unused argument/variable check. | |
Identifier should be quoted | This inspection performs SQL identifier names check. | |
Ambiguous reference | This inspection checks that column reference resolves to a single column | |
VALUES clause cardinality | This inspection checks that the number of VALUES (...) parameters matches target table column list size | |
SQL dialect detection | Detects the best matching SQL dialect for files in <Generic> dialect. | |
SQL source modification detection | Detects that database sources have changed. | |
No data sources configured | Prompts one to create a data source if there is none. | |
Each derived table should have alias | This inspection checks that each derived table should have own alias. | |
Column should be in group by clause | This inspection checks that column should be in group by clause or inside aggregate function call. | |
Constant condition | This inspection reports those conditions in the where or join clauses that are always true or false. | |
Auto-increment duplicate | This inspection checks auto_increment duplicates in MySQL, MS SQL and DB2 dialect. A table in those dialects can contain only one auto-incrementing field. | |
Index is dependent on column | This inspection checks dropping indexed columns in MS SQL and Sybase SQL Server. | |
Adding not null column without default value | Necessary to specify the default value for the new column with not null constraint. | |
Check using clause columns | This inspection checks that columns inside using clause exist in both tables. | |
Null comparison | This inspection checks suspicious comparisons with NULL. | |
Function signature | This inspection performs function signature check. | |
Statement with side effects | This inspection only runs during a read-only connection and reports statements that may lead to modification of the database | |
MySQL syntax | Provides diagnostic of MySQL parser idiosyncrasies | |
Deprecated type | Since 8.0 the 'long' type is deprecated and not recommended to use (because API for this type doesn't utilize character streams but transfer whole values each time). In Oracle, do not create a table with LONG columns. Use LOB columns (CLOB, NCLOB, BLOB) instead. LONG columns are supported only for backward compatibility. | |
Select from procedure call | Select from dblink or function that returns record require typed alias list.Scalar functions do not require alias and forbid typed alias lists completely. |
