Condtionally Appending a string

I have a SQL select statement in a script file like

Select [Var1], [Var2], [Var3] from [dbase1].[dbo]. [Table1]

I would  like to write a powershell script that I will append 't.' in front of every variable (but not database name [dbase1].[dbo]. [Table1])

For example

Select t.[Var1], t.[Var2], t.[Var3] from [dbase1].[dbo]. [Table1]

How can I make it stop before the word 'from'?

Try..

$String = "Select [Var1], [Var2], [Var3] from [dbase1].[dbo]. [Table1]"
$NewString = "$(($string -split "from")[0] -replace "\[","t.[")","$(($string -split "from")[1])" -join "From"

$NewString

what happen if there is form within the variable name

Select [Var1], [Var2 from abc], [Var3] from [dbase1].[dbo]. [Table1]

How would I pass so that I can still get this
Select [Var1], [Var2 from abc], [Var3] from [dbase1].[dbo]. [Table1]
