[![Greenkeeper badge](https://badges.greenkeeper.io/herrfugbaum/qsv.svg)](https://greenkeeper.io/)\r\n\r\n*Work in Progress*\r\n\r\n*Currently supports:*\r\n* SELECT\r\n* WHERE\r\n* ORDER BY (single column)\r\n* LIMIT\r\n\r\n![qsv demo session](https://slamcode.com/qsv/demo.gif)\r\n\r\n```bash\r\nnpm install qsv -g\r\n```\r\n\r\nOr if you're using yarn\r\n```bash\r\nyarn global add qsv\r\n```\r\nFor files with headers:\r\n```bash\r\nqsv -p \"./path/to/my/file.csv\" -h\r\n```\r\n\r\nFor files without headers:\r\n```bash\r\nqsv -p \"./path/to/my/file.csv\"\r\n```\r\nAfter loading the file you will get into REPL mode, indicated by the QSV\u003e prompt.\r\nIn REPL mode you can use SQL Queries against your .csv file.\r\n\r\n## Examples:\r\n\r\n### SELECT\r\n\r\n```sql\r\nSELECT * FROM table\r\n```\r\n\r\n```sql\r\nSELECT column1, column2 FROM table\r\n```\r\n\r\n### WHERE\r\n\r\nSupported operators\r\n\r\n| operator | meaning               |\r\n|----------|-----------------------|\r\n| =        | Equal                 |\r\n| \u003c\u003e       | Not Equal             |\r\n| \u003e        | Greater Than          |\r\n| \u003c        |

\u003c\u003e Peter\r\n\r\nSELECT * FROM table WHERE colum2 = Mexico\r\n```\r\n\r\n\r\n### ORDER BY\r\n```sql\r\n-- ASC is default for ORDER BY so this\r\nSELECT * FROM table ORDER BY column1\r\n-- is the same as:\r\nSELECT * FROM table ORDER BY column1 ASC\r\n-- For descending order you need to add DESC\r\nSELECT * FROM table ORDER BY column1 DESC\r\n```\r\n\r\ntable is just a placeholder, you don't need to specify something that makes sense, just don't leave it blank.\r\ncolumn1 and column2 are examples for the header fields.\r\n\r\nIf your .csv file doesn't have headers omit the -h option.\r\nYour table will receive enumerated headers in memory, so you can query it like this:\r\n\r\n```sql\r\nSELECT 0, 1 FROM table\r\n```\r\n\r\nOptions\r\n\r\n| Option | Verbose Version | Description                                 |\r\n| ------ | --------------- | ------------------------------------------- |\r\n| -h     |                 | Indicate that the file to parse has headers |\r\n| -d     |                 | Specifiy the delimiter of your file.
