DAO.DBEngine(0)(0).Execute" ALTER TABLE" _
& [D:\ My Documents \Access\db1.mdb] .tbl2002Transactions" _
& ALTER COLUMN fldDescription TEXT
将字段类型从二进制更改为文本。

DAO.DBEngine(0)(0)。执行ALTER TABLE ; _
& [D:\ My Documents \Access\db1.mdb] .tbl2002Transactions" _
& ALTER COLUMN fldDescription TEXT
将字段类型从二进制更改为文本。
DAO.DBEngine(0)(0).Execute "ALTER TABLE " _
& "[D:\My Documents\Access\db1.mdb].tbl2002Transactions " _
& "ALTER COLUMN fldDescription TEXT"
Changes field type from binary to text.
非常感谢Lyle,我现在就试试。

Many thanks Lyle, I''ll try that now.

莱尔,我的印象是你只能在Jet 4中使用ALTER COLUMN,
然后不用DAO。这是正确的吗?
解决方法,基思,将是:
1.更改表...创建列
2.更新......(将数据复制到新栏目中)
3.更改表格...下拉列

Lyle, I had the impression that you could only use ALTER COLUMN in Jet 4,
and then not with DAO. Is that correct?
The workaround, Keith, would be to:
1. ALTER TABLE ... CREATE COLUMN
2. UPDATE ... (to copy the data into the new column)
3. ALTER TABLE ... DROP COLUMN
