Some business data is saved in the EXCEL file, how to use SQL statements to query the data in the JAVA application for further calculation?

SQL is a query language based on the database, and the data to be queried can only be located in the database, so the usual practice is to create a temporary table in the database, then import the EXCEL data and query it with SQL statements, and finally delete the temporary table. It's easy to say, but building tables, reading EXCEL data, importing databases, and SQL queries, each step means a lot of programming work. And because the format of the EXCEL file is different and the query requirements are different, the program written is not universal, so we need to rewrite the program next time.

The aggregator SPL provides this query function, and it takes only two lines of code to complete this task.

For example, the following info.xlsx file:

If you want to find out the male employee information, write the SPL script as follows:

A1=connect () 2=A1.query ("select * from d:/excel/info.xlsx where Sex='M'")

After A2 cells get the query data, you can easily sort, group, summarize, and so on. See SPL grouping

SPL can also easily handle the following EXCEL requirements:

1. Read EXCEL files in free format, crosstab, master and child tables, etc.

2. Export and append the data to the EXCEL file, and output the EXCEL file in a preset exquisite format.

3. Read and write EXCEL files with a large amount of data

4. Merge and split EXCEL files
