FQL - File Query Language

FQL (File Query Language) is a simple and powerful file querying language designed to help you efficiently search and extract information from text files. Whether you need to analyze log files, parse JSON, or extract specific content from text files, FQL provides a versatile set of commands to simplify the process.

Introduction

FQL - File Query Language is a versatile tool for querying text files, providing a range of capabilities to efficiently work with textual data. With FQL, you can perform tasks such as extracting lines, counting words, and searching for specific content within your files. Whether you're a developer, data analyst, or system administrator, FQL simplifies the process of working with text files.

Basic Queries

SELECT

The SELECT statement is used to retrieve content (lines) from a file. You specify the file path within double quotes. For example: SELECT * FROM "C:\temp\workflow2.json";

SELECT TOP

The SELECT TOP statement allows you to select a specific number of lines from the beginning of the file. Replace 15 with the desired number of lines: SELECT TOP(15) FROM "C:\temp\workflow2.json";

SELECT TAIL

The SELECT TAIL statement lets you select a specific number of lines from the end of the file. Replace 15 with the desired number of lines:

SELECT TAIL(15) FROM "C:\temp\workflow2.json";

Searching

SELECT WHERE LIKE

Use the SELECT WHERE LIKE statement to find lines containing a particular phrase. Replace "contains this word" with your desired phrase:

SELECT * FROM "C:\temp\workflow2.json" WHERE LIKE "contains this word";

SELECT WHERE NOTLIKE

The SELECT WHERE NOTLIKE statement helps you find lines that do not contain a specific phrase. Replace "contains this word" with the phrase you want to exclude:

SELECT * FROM "C:\temp\workflow2.json" WHERE NOTLIKE "contains this word";

SELECT WHERE REGEX

The SELECT WHERE REGEX statement helps you find lines that do match a specific RegularExpression. Replace "RegexPattern" with the RegEx you want to compile and use for searching:

SELECT * FROM "C:\temp\workflow2.json" WHERE REGEX "RegexPattern";

Counting

SELECT COUNTL

To count the total number of lines in a file, use the SELECT COUNTL statement:

SELECT COUNTL * FROM "C:\temp\workflow2.json"; //return count of all Lines in this file... SELECT COUNTL TOP(20) FROM "C:\temp\workflow2.json"; // return count of lines from the top 20 lines of the file

SELECT COUNTW

To count the number of words (space-separated) in a file, use the SELECT COUNTW statement:

SELECT COUNTW * FROM "C:\temp\workflow2.json"; //return count of words from the entire file SELECT COUNTW TOP(20) FROM "C:\temp\workflow2.json"; // return count of words from the top 20 lines of the file

SELECT COUNTC

The SELECT COUNTC statement allows you to count the total number of characters in a file: SELECT COUNTC * FROM "C:\temp\workflow2.json"; //return count of characters from the entire file SELECT COUNTC TOP(20) FROM "C:\temp\workflow2.json"; // return count of characters from the top 20 lines of the file
