Trying to Import FoxPro DBF File to SQL Server

由 佐手、 提交于 2019-11-28 02:06:50
问题 As the title says, I'm trying to import a FoxPro dbf file into sql server using openrowset. At first I tried to export the DBF to an xls file and import using the Import/Export wizard. This works pretty well normally, but there is one field that sometimes holds a really long string, and this string is being truncated at 4096 characters during the export from the dbf to xls. I found an old post with instructions on how to do this using openrowset. When I try the first answer: select * from

怎么删除表空间对应的某一个数据文件

由 核能气质少年 提交于 2019-11-27 05:35:19
如果想要删除表空间的数据文件，最好且最安全的办法是，删除表空间后重建 步骤如下： 　　1，导出该表空间中的所有内容； 　　2，删除表空间：DROP TABLESPACE <tablespace_name> INCLUDING CONTENTS; 　　3，重新创建新的表空间及其数据文件； 　　4，将导出的数据导入表空间； 但是在实际应用环境中，数据文件往往比较大，表空间重建显得不太实际。 目标：删除表空间的一个数据文件 测试环境：Oracle 11.2.0.4.0 64bit 注意：此方法仅用来删除误加的表空间数据文件，如果该数据文件中已有数据，删除会导致表空间数据的不完整，建议使用上述方法删除。 首先， ALTER DATABASE DATAFILE '***.DBF' OFFLINE DROP ，这个命令用来将该数据文件从逻辑上删除，此时该文件的online_status为 recover 状态 SQL> SELECT file_id, file_name, status, online_status FROM Dba_Data_Files; FILE_ID FILE_NAME STATUS ONLINE_STATUS ---------- ----------------------------------------------------------------------

Access Visual FoxPro database from Java

问题 I've been trying to access a Visual Fox Pro database from Java for a week now. I'm getting desperate because my project is in a very tied budget and timeframe. (As any other project, I guess, hahaha) I have a .dbf , a .cdx and a .fpt files. I need to be able to look for a record, extract data, and update data. I don't have a VFP licence. I hope someone has some pointers or a working example that I can use. If the only way is buying a driver I'll be willing to consider it based on suggestions

How to import a DBF file in SQL Server

由 折月煮酒 提交于 2019-11-27 01:28:56
How can you import a foxpro DBF file in SQL Server? Use a linked server or use openrowset, example SELECT * into SomeTable FROM OPENROWSET('MSDASQL', 'Driver=Microsoft Visual FoxPro Driver; SourceDB=\\SomeServer\SomePath\; SourceType=DBF', 'SELECT * FROM SomeDBF') I was able to use the answer from jnovation but since there was something wrong with my fields, I simply selected specific fields instead of all, like: select * into CERTDATA from openrowset('VFPOLEDB','C:\SomePath\CERTDATA.DBF';''; '','SELECT ACTUAL, CERTID, FROM CERTDATA') Very exciting to finally have a workable answer thanks to

geotools修改shapefile 属性名乱码问题

由 微笑、不失礼 提交于 2019-11-26 15:43:06
在GeoServer中文社区的讨论地址为:http://opengeo.cn/bbs/read.php?tid=1701&page=e&#a 使用geotools修改shapefile之后, 发现dbf文件内容中, 属性名都成了乱码, 但属性值就不是乱码。修改之前还没有乱码的。 而且在代码中也已经通过以下方式设置过编码方式了: ShapefileDataStore shape = new ShapefileDataStore(url);shape.setStringCharset(Charset.forName("GBK")); 我的修改代码如下： /** * 修改shapefile. * @param dataStore * @param fidStr 要修改的数据对应的featureID * @return */ public static boolean updateShapeFile(ShapefileDataStore dataStore,String fidStr) { DefaultTransaction transaction = null; SimpleFeatureStore store = null; try { dataStore.setStringCharset(Charset.forName("GBK")); String[] featureNames
