Description
Describe the bug
Like Firebug (#431) Oracle also has a problem with quoted table names. Actually the same goes for schema names and column names as well. (ref). When a table is created with quoted identifiers:
CREATE TABLE "SchemaName"."table_name"
( "timestamp" TIMESTAMP (6) NOT NULL ENABLE,
"text" NVARCHAR2(50) NOT NULL ENABLE )
Identifiers with quotes are case sensitive. Identifiers without quotes are treated as uppercase. To maintain the casing of the identifier names, they should be referenced everywhere with quotes:
SELECT t."timestamp", t."text" FROM "SchemaName"."table_name" t
To Reproduce
Steps to reproduce the behavior:
- create a table like mentioned above
- create a query to retrieve records from that table
let records =
query {
for t in context.SchemName.TableName do
select ( t.Timestamp, t.Text )
}
It wil fail with Oracle.ManagedDataAccess.Client.OracleException: 'ORA-00942: table or view does not exist'
because it creates the query:
SELECT table_name.timestamp as "timestamp", table_name.text as "text" FROM SchemaName.table_name table_name
Which is interpreted by Oracle as something that cannot be found:
SELECT table_name.TIMESTAMP as "timestamp", table_name.TEXT as "text" FROM SCHEMANAME.TABLE_NAME table_name
Expected behavior
The schema object identifiers schema name, table name and column name should be quoted in statements when they were created as quoted identifiers. Preferably automatically otherwise with a flag like the one used in the Firebird solution (#431). The resulting query in this case should look like:
SELECT table_name."timestamp" as "timestamp", table_name."text" as "text" FROM "SchemaName"."table_name" table_name
