[R] R function question

[Kai Yang]

Hello List,I need to generate summary report for many tables (>200 tables). For each table, I can use the script to generate repost:
res <- dbGetQuery(con, "SELECT * FROM BIODBX.MECCUNIQUE2")view(dfSummary(res), file = "W:/project/_Joe.B/MSSQL/try/summarytools.BIODBX.MECCUNIQUE2.html")rm(res)
BIODBX.MECCUNIQUE2 is the name of table.
I have all of tables' name in a data frame. So, I'm trying to write a function to do this:
summ <- function(Tabname){  res <- dbGetQuery(con, "SELECT * FROM Tabname")  view(dfSummary(res), file = "W:/project/_Joe.B/MSSQL/try/summarytools.Tabname.html")  rm(res)}
for (i in dbtable$Tot_table){  Tabname <- as.character(sqldf(sprintf("SELECT Tot_table FROM dbtable", i)))  summ(Tabname)}
1. I created  a function summ, the argument is Tabname. I put the Tabname in the function. I hope it can be replaced one by one2. the table dbtable contents all tables' name (>200 rows), the field name is Tot_table3. I want use "for" to establish a loop, which can automatic generate a summary report for each table
but I got error message below: Error: nanodbc/nanodbc.cpp:1655: 42000: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Invalid object name 'Tabname'.  [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Statement(s) could not be prepared. <SQL> 'SELECT * FROM Tabname' 10. stop(structure(list(message = "nanodbc/nanodbc.cpp:1655: 42000: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]Invalid object name 'Tabname'.

it seems the tables' name is not successfully pass into query. can someone give me an instruction for this?
many thanks,Kai
