Parser for parsing AWQL SELECT, DESCRIBE, SHOW and CREATE VIEW statements.

 

Only the first statement is supported by Adwords API, the others are proposed by the AWQL command line tool.

 

## Examples

 

### Unknown single statement.

```go

q := `SELECT CampaignId, CampaignName FROM CAMPAIGN_PERFORMANCE_REPORT;`

stmt, _ := awql.NewParser(strings.NewReader(q)).ParseRow()

if stmt, ok := stmt.(awql.SelectStmt); ok {

    fmt.Println(stmt.SourceName())

    // Output: CAMPAIGN_PERFORMANCE_REPORT

}

```

### Select statement.

```go

q := `SELECT AdGroupName FROM ADGROUP_PERFORMANCE_REPORT;`

stmt, _ := awql.NewParser(strings.NewReader(q)).ParseSelect()

fmt.Printf("Gets the column named %v from %v.\n", stmt.Columns()[0].Name(), stmt.SourceName())

// Output: Gets the column named AdGroupName from ADGROUP_PERFORMANCE_REPORT.

```

 

### Multiple statements.

 

```go

q := `SELECT CampaignName FROM CAMPAIGN_PERFORMANCE_REPORT ORDER BY 1 LIMIT 5\GDESC ADGROUP_PERFORMANCE_REPORT AdGroupName;`

stmts, _ := awql.NewParser(strings.NewReader(q)).Parse()

for _, stmt := range stmts {

    switch stmt.(type) {

    case awql.SelectStmt:

        fmt.Println(stmt.(awql.SelectStmt).OrderList()[0].Name())

    case awql.DescribeStmt:

        fmt.Println(stmt.(awql.DescribeStmt).SourceName())

        fmt.Println(stmt.(awql.DescribeStmt).Columns()[0].Name())

    }

}

// Output:

// CampaignName

// ADGROUP_PERFORMANCE_REPORT

// AdGroupName

```
