In SQL Anywhere version 11.0 Can someone please give me syntax for ascertaining whether a table exists and also whether a column exists in the table. Thanks, Melvyn Polatchek |

The system views SYSTABLE and SYSCOLUMN are deprecated and were replaced with SYSTAB and SYSTABCOL. Here is examples for checking for groupo.products table and the column 'name' in that table against the demo database. I added the table owner to the query since it is possible that there could be multiple tables of the same name but with different ownership. Replace "groupo', 'products', and 'name' with appropriate values for your table and column. An EXISTS might be used also to simple report whether a result is found for the query. Table Query select string( su.user_name, '.', st.table_name) as qualified_table_name from sysuser su join systab st on su.user_id = st.creator where user_name = 'groupo' and table_name = 'products' Column Query select string( su.user_name, '.', st.table_name, '.', column_name ) as qualified_column_name from sysuser su join systab st on su.user_id = st.creator join systabcol stc on st.table_id = stc.table_id where user_name = 'groupo' and table_name = 'products' and column_name = 'name' Thanks guys Mel Polatchek

select * from systable key join syscolumn where table_name ='sysdbspace' and column_name='object_id' Replace 'sysdbspace' with your table name and 'object_id' with the column you are looking for. |
