ODBC database driver for Go Install: cd $GOPATH/src git clone git://github.com/weigj/go-odbc.git odbc cd odbc go install Example: package main import ( "odbc" ) func main() { conn, _ := odbc.Connect("DSN=dsn;UID=user;PWD=password") stmt, _ := conn.Prepare("select * from user where username = ?") stmt.Execute("admin") rows, _ := stmt.FetchAll() for i, row := range rows { println(i, row) } stmt.Close() conn.Close() } Tested on: SQL Server 2005 and Windows 7 SQL Server 2005 and Ubuntu 10.4 (UnixODBC+FreeTDS) Oracle 10g and Windows 7
Basically run gofix on odbc.go, comment out the conversion to complex and change calls to SQLColAttribute

SQL_INTEGER wasn't working on Windows 2003 server. I found the fix was to change C.HANDLE to C.int.
Example patch.

When query Oracle table info, the returned table_name
is limited to 15 chars:
stmt, err := conn.Prepare(` select tc.table_name, tc.comments from user_tab_comments tc where tc.table_name `)
I found table_name varchar2(30)
in user_tab_comments schema, I think the bug is related with it.

Can the driver import the fully qualified package rather than just relying on the user having installed the package locally?
See the last import in https://github.com/AllanCochrane/go-odbc/blob/master/driver/sql.go
If this change is made then the package is go gettable and the driver portion can be used with the standard database/sql package.
To explain, if I import "github.com/weigj/go-odbc/driver" then the sql.Open("odbc",...) call gives an error:
import "odbc": cannot find package
However the small change in my fork works OK.
As an aside, this is the only ODBC package that seems to work correctly with the Vertica ODBC drivers!
你好,今天使用你的插件但是在安装插件的时候报错

display missing sql.h when installing. would you please advise? Thanks.
Message:

how to get sp returen values, please give me a example , thanks.
BindParam doesnt binding int value. and Execute throws error saying COUNT error.
When I club lines 607 and 608 to a single line in odbc.go, it works fine.

I'm working with the example to the letter, with the exception of odbc.Debug = true.
Debug dumps quite a few rows successfully using default type but then it reaches one where the field length is for some reason set to -1
default type [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0] -1
panic: runtime error: makeslice: len out of range
Is there a way to more gracefully handle such a thing? It comes from calling FetchAll() or FetchOne() but neither of those return any sort of error. Or is this a bug?
conn, _ := odbc.Connect(connstr)
sql := "select CLASS_ID,CLASS_NAME from COMM_RES_CLASS where CLASS_PID='" + media_guid + "' order by CREATE_TIME"
stmt, _ := conn.Prepare(sql)
stmt.Execute()
rows, _ := stmt.FetchAll()
stmt.Close()
for _, row := range rows {
fmt.Println(row.GetString(0))
}
conn.Close()
结果中的36位guid编码被截断了,请问如何处理?
error:undefined: odbc.Connect.
Recommended use https://github.com/alexbrainman/odbc and database/sql.
Successful operation.
Hi might not be an issue but a help ... trying to compile yours to port to Windows and below error....
How can i solve it ?
Thanks
GOOS=windows GOARCH=amd64 go build -o
command-line-arguments
src/github.com/helkyd/ub_zkaccess1/ub_zkaccess1.go:11: undefined: odbc.Connect
This because the Access DB i need is on a Win PC and to access it i need to use DSN
go build text/tabwriter : no buildalbe Go source files in
Need to call SQLGetData multiple times to get long field, limit per Get is set by ODBC driver. I'm using a Windows 2003 PostgreSQL ODBC driver.
Example patch.
