Thanks for your help Markus, I change in db/drivers/mysql/describe.c case MYSQL_TYPE_DECIMAL: case MYSQL_TYPE_NEWDECIMAL: *sqltype = DB_SQL_TYPE_DECIMAL; break; and then compiled.. Now, when I tried v.in.db --overwrite table=data_wells driver=mysql database=host=localhost,dbname=Eoceno x=Este y=Norte z=Salinity_Index key=Cat output=Pozos3 The error is: Writing features... ERROR: x/y/z column must be integer or double I change the decimal type by double in mi MySQL database table and now is working.. The following (in combination with Marjus' patch) might make it work with decimal: Index: lib/db/dbmi_base/sqlCtype.c === --- lib/db/dbmi_base/sqlCtype.c (révision 36609) +++ lib/db/dbmi_base/sqlCtype.c (copie de travail) @@ -17,6 +17,8 @@ return DB_C_TYPE_DOUBLE; case DB_SQL_TYPE_DOUBLE_PRECISION: return DB_C_TYPE_DOUBLE; +case DB_SQL_TYPE_DECIMAL: + return DB_C_TYPE_DOUBLE; case DB_SQL_TYPE_SERIAL: return DB_C_TYPE_INT; } But I'm not sure whether it might have any negative consequences to automatically associate decimal with double. I can't think of anything obvious, but needs testing. Moritz ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

[GRASS-user] v.in.db accept DECIMAL'S?
Hi all, I'm trying to create a new vector (points) map from a mysql database table v.in.db --overwrite table=data_wells driver=mysql database=host=localhost,dbname=Eoceno x=Este y=Norte z=Salinity_Index key=Cat output=Pozos but I get this error: WARNING: MySQL driver: column 'Salinity_Index', type 246 is not supported Writing features... Segmentation fault In my MySQL database table Salinity_Index are decimals numbers and the column type is DECIMAL(6,3) NULLMy question is, Can I work with decimals number in module v.in.db? Need I work with decimals numbers in other column type, maybe FLOAT, DOUBLE? I'm using GRASS 6.4.0RC3 in ubuntu Hardy and MySQL 5.0.51a-3ubuntu5.4 Some advice?
