1.0.9: Fix reading int values

Summary

This release fixes an issue when calling rows.Scan(&result) with an int value. This failed for large values like 100000000 with the following error:

sql: Scan error on column index 0, name "COL": converting driver.Value type float64 ("1e+08") to a int64: invalid syntax

Please note that reading non-integer numbers like 1.1 into a int64 variable will still fail with the following error message:

sql: Scan error on column index 0, name "COL": converting driver.Value type string ("1.1") to a int64: invalid syntax

The release also now returns the correct error from rows.Err(). Before, this only returned driver.ErrBadConn.

Bugfixes

• #113: Fixed Scan() with large integer numbers
• #111: Return correct error from rows.Err()

1.0.8: Fix inserting double values

Summary

This release fixes an issue inserting double values with a prepared statement.

Details of the fix:
The driver serializes commands to the database as JSON. When inserting values into a DOUBLE column, the database expects the JSON to contain numbers with a decimal point, e.g. 42.0. When using values like 42 or 42.0 in stmt.Exec(), the driver omitted the decimal point. This caused the query to fail with error

E-EGOD-11: execution failed with SQL error code '00000' and message 'getDouble: JSON value is not a double

Bugfixes

• #108: Fixed inserting double values with a prepared statement

1.0.6: Fix escaping of URL path

Summary

This release fixes an issue when the user specifies a URL path containing characters like ? or %. These were incorrectly escaped. We fixed this and now the URL path is used without modification when connecting to the database.

Bugfix

• #104: Fixed encoding of URL path

1.0.5: Escape connection string

Summary

This release supports using ; in the connection string. When using the builder like this, it will automatically escape the semicolon:

connectionString := exasol.NewConfig("<username>", "<password>").
                           Host("<host>").
                           Port(8563).
                           ClientName("My Client; Version abc").
                           String()

When using the connection string directly, you need to escape ; with a \:

connectionString := `exa:localhost:1234;user=sys;password=exasol;clientname=My Client\; Version abc`

Additionally this release also support specifying an URL path when creating the WebSocket connection to the database. This is only required in special situations and should not be used when connecting to an Exasol database.

1.0.4: Fixed `IMPORT LOCAL CSV FILE`

Summary

This release fixes the detection of IMPORT LOCAL CSV FILE. Before, the Go driver also detected this inside strings which broke e.g. running the following INSERT statement:
