When creating a spatial table and recovering the geometry using the RecoverGeometryColumn function if you don't specify the geometry column as lower case you end up getting a 'violates Geometry constraint [geom-type or SRID not allowed]' error.

Am I doing something wrong or I have missed some documentation somewhere?

  • I had the same problem. My issue was that I was setting that I was expecting points as a type via AddGeometryColumn and then trying to put Polygons. – grasshopper Jan 08 '15 at 21:09

To give an example:

  1. Create a table that has a spatial column

    CREATE TABLE "test1" (
    "PK_UID" INTEGER PRIMARY KEY AUTOINCREMENT,
    "Geometry" MULTIPOLYGON)
    
  2. Recover the geometry

    SELECT RecoverGeometryColumn('test1', 'Geometry', 2, 'MULTIPOLYGON',2);
    
  3. Look at the triggers that were created

    select * from sqlite_master where type='trigger' and lower(tbl_name)='test1'
    

Results:

    CREATE TRIGGER "ggi_test1_Geometry" BEFORE INSERT ON "test1"
    FOR EACH ROW BEGIN
    SELECT RAISE(ROLLBACK, 'test1.Geometry violates Geometry constraint [geom-type or SRID not allowed]')
    WHERE (SELECT type FROM geometry_columns
    WHERE f_table_name = 'test1' AND f_geometry_column = 'Geometry'
    AND GeometryConstraints(NEW."Geometry", type, srid, 'XY') = 1) IS NULL;
    END

    CREATE TRIGGER "ggu_test1_Geometry" BEFORE UPDATE ON "test1"
    FOR EACH ROW BEGIN
    SELECT RAISE(ROLLBACK, 'test1.Geometry violates Geometry constraint [geom-type or SRID not allowed]')
    WHERE (SELECT type FROM geometry_columns
    WHERE f_table_name = 'test1' AND f_geometry_column = 'Geometry'
    AND GeometryConstraints(NEW."Geometry", type, srid, 'XY') = 1) IS NULL;
    END

Compare with what is in the geometry_columns table

    select * from geometry_columns

Results:

f_table_name f_geometry_column type coord_dimension srid spaitial_index_enabled

test1 geometry MULTIPOLYGON XY 2 0

Conclusion: Note that the geometry_columns table the f_geometry_column is specified as 'geometry' but the trigger is looking for 'Geometry'. This causes the 'Geometry constraint [geom-type or SRID not allowed]' issue. So the fix is keep you spatial column names lower case.

  • I've tried this but I'm still getting the same error with "CREATE TABLE Sessions([SessionId] TEXT NOT NULL PRIMARY KEY, [SessionCompletedDate] TEXT NOT NULL, [shape] POINT NULL)", "SELECT RecoverGeometryColumn('Sessions', 'shape', -1, 'POINT', 2)", "SELECT CreateSpatialIndex('Sessions', 'shape')", – Chucky Oct 26 '15 at 10:48
