database is already looking at the case of VFP: sample database in a text given, here are no longer detailed, only briefly introduce the production process.
The production steps are as follows:
First, create a new form Form1 and set its Caption property to "Locate and locate records in a table", set the Width property value to the 290,height property value set to the 226,autocenter property value set to. T, and save it as " Modify the records in the datas

If I have a table T which has two columns, as shown in:
A
B
1
3
1
3
2
5
2
4
3
7

Where a column value of 1 corresponds to the B column value of the 3,a column value of 2 corresponds to the value of column B is two, one is 5, one is 4, we are to List 2 5,2 4 of this two records.The first method uses the Max and Min functio
or an unrecoverable error occurs, but you know how to regenerate the table using the corresponding CREATE TABLE statement, you can regenerate a new. frm file and and your data files and index files ( If there is a problem with the index file, use the method above to reconstruct a new one. First make a copy of the data and index file, and then delete the original file (delete all the records in the data directory about the table). Start the MySQL service and create a new table using the original
when a datasheet in Excel is copied to Word, the table style often crosses the line and the content is truncated.
Do you have a problem with this? There are two ways to fix this.
Automatic rearrangement of full content
The reason for this is that there are cases like this, because the AutoFit property of a table in a Word document defaults to "Adjust table by content," If the Excel worksheet you want to convert has more data width than
How to make an Excel datasheet with a page subtotal
Similar print style in some financial software has been implemented, so we can use Excel with the function to achieve this effect.
Already have a master with VBA code or small tools to achieve. But for most cousins, using VBA code is a bit tricky.
The following figure, for example, assumes that we need to print 40 lines of content per page.
First, create secondary columns

The Oracle tutorial you are looking at is the strategy for Oracle datasheet partitioning. This article describes the need to partition the hospital information system by statistical analysis of the table, the need to partition the table to select the partition key, that is, to find the columns included in your Partition key (table properties), the management of large data more meaningful, the work of this article is implemented under the Oracle8.1.6.
The example in this article describes a method for quickly creating a model of a nonstandard name datasheet thinkphp. Share to everyone for your reference. The specific methods are as follows:
Non-standard name datasheets, such as: Cow_archives_4, naming document model data tables such as common Uzibo cms,08cms like named methods, assuming that the data table prefix is configured in the configuration file:
Copy Code code as follows:

You have an Excel datasheet with approximately 50,000 records (rows), a total of 9 columns, where 3 characters are up to 4000 characters long.Want to import this table into the database for analysis, query, never want to try to success from the beginning, spent nearly one months.
1. Use MySQL to import, refer to my other two blog:

System environment:
1, operating system: Windows Server, machine memory 128M
2. Database: Oracle 8i R2 (8.1.6) for NT Enterprise Edition
3, Installation path: C:\ORACLE
Implementation steps:
1. Export with exp tools
2. Use the SHOW=Y option when importing, log option
3. View and edit log files

statement, after testing is not a problem, of course, before testing, you should back up the data, and then after testing and then restore the database, about how to back up the database method, has been said before, this is relatively simple.Here's another note: Delete does not require column names and wildcards, it deletes the entire row instead of the column, deletes the specified column, uses the UPDATE statement, and the DELETE statement deletes rows from the table, or even deletes all row
by using PL/SQL bulk query fetching, each column of data in Excel is copied and pasted into the new intermediate table, which is sticky when pasted, that is, some columns will be inserted into the whole column from the second third row, causing the data to be confused, and then it does not support the bulk deletion of the entire column of data, So it's the best way to import an entire Excel table at once.The first step:Select all of the data in Excel that you want to insert into Oracle: ( must b
