问题 I have written lots of the queries but I'm struggling with this one. I get the run-time error 3065 when I run the following sql. Dim db As DAO.Database Dim sqlstring As String Set db = DBEngine(0).Databases(0) sqlstring = "SELECT ebk.hr_leav_amnt AS hr_clia_hour, ebk.hr_leav_type, ebk.hr_leav_code, ebk.hr_empl_code, ebk.hr_loadg_amt AS hr_loadg_amt, 'Leave Pay' AS hr_provision, mst.hr_paym_code, mst.hr_base_hour, '' AS hr_splt_accr, mst.hr_leav_abbr, ype.hr_norm_pcnt, ype.hr_allw_amnt"

问题 When linking to an external data source via ODBC (especially an AS/400), I often run into cryptic field names on the other side, where a data dictionary is not available. In the rare event that I'm able to get the field descriptions from the other db, I would like to be able to import them all at once, rather than copy/paste each description into the table design form one at a time. I wasn't able to find this in the system tables, so I don't know where this metadata is stored. Any ideas on

问题 I have a project where users will need to fill out an Excel file and then export the data to an Access database. The data collected in the Excel file will need to be exported in 3 steps: (1) export data set 1 record, (2) query Access for the primary key (auto-number) of the newly imported record, (3) export data set 2 record, which includes the primary key populated as the foreign key. I am able to accomplish the first step by establishing and opening an ADODB connection. However, I am

问题 I have not been able to find a way to join 4 or more tables using outer join in MSAccess. It works in SQL Server, but not Access. I don't believe it is possible. I have tables A, B, C, D and E. I need to join the tables like so: A left outer join B A left outer join C A inner join D B inner join E Access won't let you use conventional joins in the where clause when you use LEFT/RIGHT/INNER JOINS in the FROM clause. If you do, I get very, very vague errors like "JOIN expression not supported"

问题 Our access client generates on the fly SQL inserts, update and delete instructions to be sent on a MS-SQL Server. Most users have the runtime version of Access 2007, and a few use the complete MS-Access version, 2003 or 2007. This morning one of our new users abroad, using a french/complete version of Access 2003, was unable to update data containing boolean fields. It appeared that these fields are, in the french version of Access, populated with "Vrai/Faux" instead of "True/False" values.

问题 I have been trying to access the MS Access database file residing on my machine and it works just fine when I have office installed. When I try to use the same code on a machine that does not have office installed/driver installed it throws up an error " Microsoft.ACE.OLEDB.12.0 provider is not registered " I followed up on this post Microsoft.ACE.OLEDB.12.0 provider is not registered but the solution here is to install the redistributable physically.while I would like to do it

问题 I need to insert the dataset records(C#) into the MS Accessdatabase table. I need to do the bulk insertion of records. How can I do this in C# 回答1: For this sort of task, consider using the data adapter abstraction. With an Microsoft Access database, you can use the OleDbDataAdapter implementation as shown in the example below: // Prerequisite: The data to be inserted is available in a DataTable/DataSet. var data = new DataTable(); data.Columns.Add("CompanyName", typeof(string)); data.Columns
