SQL Expression for Date Range in PowerBI Query

Hi

I have the expression below which seeks to get certain fields from a table where the date is between the two dates in the expression. However, there is something wrong with the statement - what is it?

Thank YOu

The code is

let
Source = GetConsolidatedSQLData("Select accountcode, branchcode, departmentcode, transactiondate, transactionamount, periodno, yearno, periodid from GLTRAN where transactiondate between '1/7/2018 00:00:00' and '2/7/2018 00:00:00'"),

#"Changed Type" = Table.TransformColumnTypes(Source,{{"AccountCode", type text}, {"BranchCode", type text}, {"DepartmentCode", type text}, {"PeriodNo", type text}, {"YearNo", type text}, {"PeriodID", type text}, {"CompanyCode", type text}, {"TransactionAmount", Currency.Type}, {"TransactionDate", type date}})

in
#"Changed Type"

the error I get is
